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.

# valence_inventory
The inventory system.
This module contains the systems and components needed to handle
inventories. By default, clients will have a player inventory attached to
them.
# Components
- [`Inventory`]: The inventory component. This is the thing that holds
items.
- [`OpenInventory`]: The component that is attached to clients when they
have an inventory open.
# Examples
An example system that will let you access all player's inventories:
```
# use bevy_ecs::prelude::*;
# use valence_inventory::*;
# use valence_client::Client;
fn system(clients: Query<(&Client, &Inventory)>) {}
```
