Open to discussion!

I watched you PyCon DE 2022 talk on this topic and was fascinated by the effort. I think it'd be great in a setuptools extensions or minimal binding library can come about from this effort.

I'm newcomer to zig, so I definitely don't have everything right with these changes. I am open to discussion to help with this. Feel free to comment or close.
