Consider adding a py.typed file to the package

[peteris-zealid]

Hello,

I ran mypy on the codebase and it revealed only a few minor issues. Nothing that the end user would ever care about. On one hand it might be slightly irresponsible to add a py.typed marker without setting up a type checker to run at each commit, but on the other hand automatically generated stubs will be of much lower quality and should be avoided for practical purposes.

I spoke a bit too soon.

It seems that in crypto_utils.py the type for password in various places should be Optional[bytes] not str.

Hi @peteris-zealid,

Sorry, took me a while to get to this one. I added py.typed, fixed all the mypy warnings and added a mypy checker workflow to the repo :). See linked PR.

Hi, I thought this was a closed issue, but thank you for letting me know. Sometimes it pains my heart to see you not getting paid for all the quality work (and support) you are doing on this lib.

Well, my GitHub Sponsors registration request finally got processed yesterday, so there's an avenue now... ;)

Not that I have grand expectations about the revenue that would generate, though :)
