Registry Redesign (#361)
## Description

- Revert the "biomes/dimensions as entities" idea since it caused too
many problems without much to show for it.
- Make use of `valence_nbt`'s serde support in `valence_biome` and
`valence_dimension`.
- Reduce boilerplate, reorganize `valence_registry` a bit.
- Tweak default biome registry such that `BiomeId::default` always
corresponds to "minecraft:plains".
- Add `Option` and unit variant support to `valence_nbt`'s serde impl.

serde support for valence_nbt + fixes. (#352)
## Description

- Reorganize `valence_nbt` and feature flag the different parts. SNBT
and binary serialization are each behind their own flags.
- Add optional serde support to `valence_nbt` behind the `serde` flag.
This is useful for end users working with `valence_nbt` and allows us to
simplify some code in `valence_biome` and `valence_dimension`.

Note that this includes a `Serializer` and `Deserializer` for `Compound`
and _not_ the binary and SNBT formats. In other words, it's not possible
to go directly from an arbitrary data format to binary NBT and vice
versa, but it _is_ possible to go to and from `Compound` and finish the
(de)serialization this way. I consider this an acceptable compromise
because writing fast and correct serialization routines for `Compound`
becomes more difficult when serde is in the way. Besides, the
intermediate `Compound` often needs to be created anyway.
- Fixed unsound uses of `std::mem::transmute` in `valence_nbt` and
elsewhere. Using `transmute` to cast between slice types is unsound
because slices are `#[repr(Rust)]` and the layouts are not guaranteed.
`slice::from_raw_parts` is used as the replacement.

Reorganize Project (#321)
## Description

- `valence` and `valence_protocol` have been divided into smaller crates
in order to parallelize the build and improve IDE responsiveness. In the
process, code architecture has been made clearer by removing circular
dependencies between modules. `valence` is now just a shell around the
other crates.
- `workspace.packages` and `workspace.dependencies` are now used. This
makes dependency managements and crate configuration much easier.
- `valence_protocol` is no more. Most things from `valence_protocol`
ended up in `valence_core`. We won't advertise `valence_core` as a
general-purpose protocol library since it contains too much
valence-specific stuff. Closes #308.
- Networking code (login, initial TCP connection handling, etc.) has
been extracted into the `valence_network` crate. The API has been
expanded and improved with better defaults. Player counts and initial
connections to the server are now tracked separately. Player counts
function by default without any user configuration.
- Some crates like `valence_anvil`, `valence_network`,
`valence_player_list`, `valence_inventory`, etc. are now optional. They
can be enabled/disabled with feature flags and `DefaultPlugins` just
like bevy.
- Whole-server unit tests have been moved to `valence/src/tests` in
order to avoid [cyclic
dev-dependencies](https://github.com/rust-lang/cargo/issues/4242).
- Tools like `valence_stresser` and `packet_inspector` have been moved
to a new `tools` directory. Renamed `valence_stresser` to `stresser`.
Closes #241.
- Moved all benches to `valence/benches/` to make them easier to run and
organize.

Ignoring transitive dependencies and `valence_core`, here's what the
dependency graph looks like now:

```mermaid
graph TD
	network --> client
	client --> instance
	biome --> registry
	dimension --> registry
	instance --> biome
	instance --> dimension
	instance --> entity
	player_list --> client
	inventory --> client
	anvil --> instance
	entity --> block
```

### Issues
- Inventory tests inspect many private implementation details of the
inventory module, forcing us to mark things as `pub` and
`#[doc(hidden)]`. It would be ideal if the tests only looked at
observable behavior.
- Consider moving packets in `valence_core` elsewhere. `Particle` wants
to use `BlockState`, but that's defined in `valence_block`, so we can't
use it without causing cycles.
- Unsure what exactly should go in `valence::prelude`.
- This could use some more tests of course, but I'm holding off on that
until I'm confident this is the direction we want to take things.

## TODOs
- [x] Update examples.
- [x] Update benches.
- [x] Update main README.
- [x] Add short READMEs to crates.
- [x] Test new schedule to ensure behavior is the same. 
- [x] Update tools.
- [x] Copy lints to all crates.
- [x] Fix docs, clippy, etc.

Update to 1.19.4 (#302)
## Description

Closes #291

- Update extractors to support Minecraft 1.19.4
- Update code generators.
- Changed generated entity component names to avoid name collisions.
- Update `glam` version.
- Added `Encode` and `Decode` for `glam` types in `valence_protocol`.
- Fixed inconsistent packet names and assign packet IDs automatically.
- Remove `ident` and rename `ident_str` to `ident`.
- Rework registry codec configuration. Biomes and dimensions exist as
entities.`BiomeRegistry` and `DimensionTypeRegistry` resources have been
added. The vanilla registry codec is loaded at startup.

### Issues
- Creating new instances has become more tedious than it should be. This
will be addressed later.

## Test Plan

Steps:
1. Boot up a vanilla server with online mode disabled.
2. Run the `packet_inspector`.
3. Connect to the vanilla server through the packet inspector to ensure
all packets are updated correctly.
4. Close the vanilla server and try some valence examples.

Refactor valence_protocol (#253)
## 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`.

Add a simple SNBT parser (#201)
To implement the hoverEvent show_item, we need an SNBT parser and a SNBT
serializer.
An SNBT parser is implemented in this commit.

Support NBT lists of type TAG_End (#181)
In NBT, lists are allowed to have the element type TAG_End iff their
length is zero. This adds an explicit `List::End` enum variant to
valence_nbt.
