adding py.typed to enable mypy, if used as library

[daringer]

This package is well typed, in order to use it as a library it should be marked as typed as explained here: https://mypy.readthedocs.io/en/stable/installed_packages.html#creating-pep-561-compatible-packages

This PR adds a py.typed file and includes it inside pyproject.toml so anyone including this package as a library/dependency can use mypy for type-checking.

Thanks! Though looking at the provided link, shouldn't the py.typed file be located in the fido2 directory rather than the root?

[daringer]

yes, you are right, the final py.typed file did not end up where it should. Made the necessary changes and tested like that (with the repository being the current work directory):

# set up virtual env
$ python -m venv /tmp/my-test-venv

# install python-fido2 into virtual env
$ /tmp/my-test-venv/bin/python -m pip install .

# check py.typed is at the right spot
$ stat /tmp/my-test-venv/lib/python-3.*/site-packages/fido2/py.typed

You shouldn't need the change to pyproject.toml, the file should get included anyway.

Indeed, updated!

Thanks! Merged!
