feat: add type annotations

[nstarman]

From testing v0.0.4 I found that there are some missing type annotations. This PR adds type annotations to quaxify, makes _Quaxify generic wrt the function, and adds a few miscellaneous types.

Test failure is from the pre-commit pyright being out of date. This passes when pyright is updated!

LGTM!

[patrick-kidger]

Why remove this?

[nstarman]

Newer ruff doesn't require it. It surfaces a warning saying that it's being deprecated.

Update pyright in this MR as well? :)

I actually don't know how pre-commit is selecting the pyright version. Is there a reason this repo runs pre-commit manually, versus using pre-commit.ci ?

[patrick-kidger]

The version is specified in .pre-commit-config.yaml. The pre-commit command itself is ran during tests.

I guess I'd spin that around, why use an external service for something that is already simple enough to do manually?

Oops, duh. I git-exclude my pre-commit-configs once I lock in the set of hooks so that I never think about it and let pre-commit.ci wholly manage upgrading the hooks. So it wasn't showing being changed in this PR for git add -A!

Personally I (and astropy) do it for

1. Automatic upgrading of hooks.
2. Option to comment pre-commit.ci autofix for contributors that don't use pre-commit.

[patrick-kidger]

Oh, the autofixing PRs is quite nice. Indeed sometimes we do find new contributors who haven't used pre-commit locally. (Although in my experience pretty much everyone uses pre-commit, so this doesn't come up super frequently.)

Anyway, merged! This PR looks good to me. If this now has everything you want I'm happy to do a new versioned release as well. (Or a little later if you find there's some other tweaks still needed.)
