## Description

<!-- Provide a brief description of the PR's purpose here. -->

Proof of concept for adding type annotations to pyribs. For type
checking, I am currently using [ty](https://docs.astral.sh/ty/) -- it
lines up well with Ruff in terms of being really fast. However, ty is
not quite production ready, so support for it in pre-commit and other
tools is not quite ready yet (e.g., ALE:
dense-analysis/ale#4971). However, I found it
mostly sufficient for my purposes.

In the future, the goal will be to add type annotations everywhere else
in pyribs.

This regex is helpful for catching docstrings that have old types:
```
grep -r "^ *[a-z_]* (.*):" ribs
```

## TODO

<!-- Notable points that this PR has either accomplished or will
accomplish. -->

- [x] Add ty to dev deps
- [x] Add ty to pre-commit -- see
astral-sh/ty#269
- [x] Skip ty in pre-commit CI
- [x] Add ty instructions to docs
- [x] Add type annotations in ribs.visualize
- [x] Matplotlib imports in ribs.visualize had to be made more specific;
see notes on submodules here: astral-sh/ty#445
- [x] `plt.axes(projection="3d")` isn't typed for the correct `Axes3D`
object, so I had to add some ignores; see
matplotlib/matplotlib#29341
- [x] Add py.typed and include it in MANIFEST.in
