Build and publish wheels for python using maturin

[tripcher]

Hey! I think that will be great if we can use squawk in python. For example, for integration with alembic. I would like to install squawk from pip pip install squawk and use it. it seems we can use maturin for building and publishing.

I can try to add maturin if you don't mind.

yeah I'm down for adding it, I used npm because it was easiest to distribute binaries (all the npm does is run a install script which downloads the binaries from GitHub)
