Type hints

[radarhere]

Hi. Just wondering what it would take to add a PEP 561 py.typed file to this project?

I see you have some type hints already. Would you welcome pull requests to improve upon this?
Does atheris aim to continue supporting Python 3.6, or can that be updated now that 3.6 is EOL?
Would a py.typed file be acceptable once pytype passes?

I created #86 to test the waters, and then #87 to add most of the remaining type hints. However, that has yet to be reviewed.

If you are just taking your time to get to it, no problem. However, if you think that it would be better for me to create stubs through https://github.com/python/typeshed, let me know.

I've created python/typeshed#12462

The typeshed issue has now been merged, so https://pypi.org/project/types-atheris/ now exists.

Note to maintainers here: the existence of types-atheris does not invalidate this issue! It would be better for type annotations to come from first-party.
