mypy is what's failing CI:

You can run this locally to see what errors it's raising. When mypy reports nothing locally it should all pass in CI too:

python -m mypy webauthn

As in #166 fixing some of these probably involves adding # type: ignore[attr-defined] here and there.

@MasterKale mypy goes belly up when I install pydantic v1

py_webauthn/.venv/lib/python3.11/site-packages/pydantic/env_settings.py:22: error: INTERNAL ERROR -- Please try using mypy master on GitHub:
https://mypy.readthedocs.io/en/stable/common_issues.html#using-a-development-mypy-build
If this issue continues with mypy master, please report a bug at https://github.com/python/mypy/issues
version: 1.4.1

I think latest commit will finally make mypy happy but I can't run it myself.

This is looking all but ready to go @jpaniagualaconich, thank you again for taking the time to prepare this PR. Just had one final question before I accept.

[MasterKale]

Hey @jpaniagualaconich, I know it's been a few days but I do intend to merge this after I get back from TPAC and my schedule clears up a bit to take your changes out for a spin. Thanks for your patience!

[MasterKale]

Alright, this looks good to me. Thank you for your contribution @jpaniagualaconich 🎉
