Added a caching layer to the CI
This creates a cache on first run (should exist because of this pr now)
The hash is calculated from the Cargo.toml files (recursively if i've
done it correctly)
So whenever a Cargo.toml file changes, it invalidates the cache.
Local crates are _not_ cached, so they get recompiled regardless, but it
already shaves off like half the total time from the action runners.
## Description
Adds a `RawPacket` type to `valence_protocol`. This type simply reads
and writes data to a slice, analogous to the `RawBytes` type in the same
module.
## Test Plan
Steps:
1. `cargo t -p valence_protocol`
## Description
Change the issue and pull request templates.
- Remove HTML comments from the markdown because it's often not deleted
and takes up space in the final commit description.
- Remove the "related" section in the PR template because links to other
issues will naturally end up in the "description" section.
- Remove some placeholder text in the feature request template.
- Remove the check boxes from the bug report template to avoid creating
"tasks".
- The number of sections in the bug report template was a bit daunting
IMO so I trimmed it down a bit.

This mostly adds docs, but it also adds (and documents) some new helper
functions:
- `set_title()` - Allows us to put `must_use` on `replace_title`
- `set_slot()` - Allows us to put `must_use` on `replace_slot`
- `set_slot_amount()` - Allows users to modify stack counts without
cloning the entire stack and replacing it. Useful if the stack has a lot
of NBT data.
- `first_empty_slot()`
- `first_empty_slot_in()` - Useful, trivial to provide

## Description
In the [examples of the `valence`
crate](https://github.com/valence-rs/valence/tree/main/crates/valence/examples),
the `setup()` functions are currently [exclusive
systems](https://bevy-cheatbook.github.io/programming/exclusive.html).
My reasoning for making these a standard system is twofold:
- Exclusive systems can be considered an advanced Bevy topic. I don't
think you should be using advanced concepts in examples meant to be an
introduction to the way this project/framework is used.
- In instances where developers try to use these examples, adding
another startup system would result is running the systems sequentially.
That leaves performance on the table (albeit only during startup).

## Description
Combines the `EncodePacket` and `DecodePacket` trait into a single
`Packet` trait. This makes `valence_protocol` simpler and easier to use.
This can be done because all packets were made to be bidirectional in
#253.
Additionally, a `packet_id` method has been added. This should help with
#238.
## Test Plan
Steps:
1. Run examples, packet_inspector, etc. Behavior should be the same.
## Description
- Remove duplicate packet definitions by using `Cow`.
- Rename packets to match yarn mappings.
- Remove some top-level re-exports.
- Move every packet into its own module for consistency.
- Move packet-specific types from the `types` module into the
appropriate packet module.
- Remove internal use of `EncodePacket`/`DecodePacket` derives and move
packet identification to `packet_group`. This can be done because there
are no duplicate packets anymore.
- Simplify some events.
In a future PR I plan to clean things up further by properly bounding
packet data (to prevent DoS exploits) and fixing any remaining
inconsistencies with the game's packet definitions.
## Test Plan
Behavior of `valence_protocol` should be the same.
Steps:
1. Use the packet inspector against the vanilla server to ensure packet
behavior has not changed.
2. Run the examples.
3. Run `valence_stresser`.

## Description
This adds an API for getting the wall / attachable variant of a block.

## Description
Take 3 of #247.
I've added a minimal chat example - ignoring chat signing, etc. It's in
the file `crates/valence/examples/chat.rs`.
## Test Plan
Manual, unfortunately :(
Steps:
1. Open two minecraft clients, with two separate accounts (or usernames
if using offline mode)
2. Connect to the server in both clients
3. Type a chat message, checking it appears to both clients, with the
correct username.
4. Type a command, checking it appears only to the sender.

An implementation of a Minecraft server stresser for testing purposes.
The potential of this pull request is to implement a minimal stresser
binary package that would be bound to the local `valence_protocol`
package, so it would be always up to date with the latest Valence
Minecraft protocol implementation.
The MVP version is going to be able concurrently connect headless
clients to a target Minecraft server.

## Description

Dropping items is heavily coupled to inventories. Clients also predict
state changes when they try to drop items, so we need to be able to
replicate that change in order to stay in sync.
This will also remove `DropItem` events in favor of just `DropItemStack`
events. Having 2 event streams that basically mean the same thing seems
verbose and error prone.
As of right now, these changes require the event loop to have a
reference to the client's inventory. This seems like something we are
going to need to do a lot more of to complete #199.

This is my first time contributing here so I was pretty unfamiliar with
the codebase and may have done some things incorrectly.
## Description
- Added a sound extractor to extract sound event ids and identifiers
- Added a `Sound` enum (with a build script) to represent sound effects
- Added a `play_sound` method to `Instance` and `Client`
- Re-implemented sound effects in the parkour example
## Test Plan
I tested this using the sounds I added to the parkour example.

Currently the player list will only update upon connection. Should

Printing ping per keepalive packet on a different computer on my
network. It seems to work fine but would need extra feedback.

## Description
<!-- Describe the changes you've made. You may include any justification

I've used the popular `owo-colors` library to colourise the output of
the `packet_inspector`.
This makes it a lot easier to see who's sending what for debugging
purposes.
In future, I'd like to be able to filter out common, low-information
packets like `SetPlayerPosition` and `KeepAlive` as well, but that's not
in this PR.
## Test Plan
No tests - just eyeball 😄.

fixes#233
This PR redesigns Valence's architecture around the Bevy Entity
Component System framework (`bevy_ecs` and `bevy_app`). Along the way, a
large number of changes and improvements have been made.
- Valence is now a Bevy plugin. This allows Valence to integrate with
the wider Bevy ecosystem.
- The `Config` trait has been replaced with the plugin struct which is
much easier to configure. Async callbacks are grouped into their own
trait.
- `World` has been renamed to `Instance` to avoid confusion with
`bevy_ecs::world::World`.
- Entities, clients, player list, and inventories are all just ECS
components/resources. There is no need for us to have our own
generational arena/slotmap/etc for each one.
- Client events use Bevy's event system. Users can read events with the
`EventReader` system parameter. This also means that events are
dispatched at an earlier stage of the program where access to the full
server is available. There is a special "event loop" stage which is used
primarily to avoid the loss of ordering information between events.
- Chunks have been completely overhauled to be simpler and faster. The
distinction between loaded and unloaded chunks has been mostly
eliminated. The per-section bitset that tracked changes has been
removed, which should further reduce memory usage. More operations on
chunks are available such as removal and cloning.
- The full client's game profile is accessible rather than just the
textures.
- Replaced `vek` with `glam` for parity with Bevy.
- Basic inventory support has been added.
- Various small changes to `valence_protocol`.
- New Examples
- The terrain and anvil examples are now fully asynchronous and will not
block the main tick loop while chunks are loading.
# TODOs
- [x] Implement and dispatch client events.
- ~~[ ] Finish implementing the new entity/chunk update algorithm.~~ New
approach ended up being slower. And also broken.
- [x] [Update rust-mc-bot to
1.19.3](https://github.com/Eoghanmc22/rust-mc-bot/pull/3).
- [x] Use rust-mc-bot to test for and fix any performance regressions.
Revert to old entity/chunk update algorithm if the new one turns out to
be slower for some reason.
- [x] Make inventories an ECS component.
- [x] Make player lists an ECS ~~component~~ resource.
- [x] Expose all properties of the client's game profile.
- [x] Update the examples.
- [x] Update `valence_anvil`.
- ~~[ ] Update `valence_spatial_index` to use `glam` instead of `vek`.~~
Maybe later
- [x] Make entity events use a bitset.
- [x] Update docs.

- Extends `Text`'s `Deserialize` impl to allow for deserializing JSON
data types other than objects.
- Add additional `From` impls for `Text`.
- Better `Debug` impl for `Text`.
- Tweaked text unit tests.
Adds `tracing` to `valence_protocol` so we can log debug info about
partially decoded packets. `packet_inspector` has been set to print log
messages at the debug level.
Adds the `valence_anvil` crate for loading anvil worlds. It can only read blocks and biomes currently. Support for saving data is to be added later.

- Fix performance issues related to writing individual bytes instead of
using `Write::write_all`.
- Make manual implementations of `Encode` and `Decode` easier:
- Remove `encoded_len` method from `Encode`
- Split `Packet` trait into `EncodePacket` and `DecodePacket`.
- Simplify derive macros.
- automatically handle CloseContainer packet so the client updates open_inventory
- Use `Option<InventoryId>` for `open_inventory` on client
