Finish typing support.

[jschwartzentruber]

This finishes the work by @nth10sd in #115 . Much of the nicer syntax depends on __future__ annotations which has other caveats, so I've backported this to 3.6 for now.

This also enables mypy in pre-commit, enables Python 3.10 CI, and enables lint across all Python versions in CI.

Supersedes #115.

Yes, that's because of missing annotations for pytest fixtures when pytest isn't installed. Using tox or pre-commit will install pytest to avoid these errors.

Yes, you're right!
