type information

I believe you must include a marker file, py.typed in the published package in order for the type hints to be usable downstream. See https://peps.python.org/pep-0561/#packaging-type-information.

Also, I notice that mypy/pyright aren't used in your CI, which seems like a gap that should be closed.

@tamird Good first issue, thanks! We'll add mypy checks on CI in the near future.
