Add release pipeline, fixes #116

[twizmwazin]

This release pipeline uses cibuildwheel to build wheels for most common platforms and also an sdist for platforms not covered. All the build tools and publishing action are by PyPA to hopefully observe best practices. One notable thing is that this does not generate a python 2 wheel, however python 2 users will still be able to install with the provided sdist. If that is an issue I can look at adding another set of jobs for python 2 specifically using an older version of cibuildwheel.

I have tested the build jobs and the output looks good, I haven't been able to validate the publish job. In order for the upload to succeed, you'll need to configure a trusted publisher as documented here.

Fixes #116

It seems like the ARM64 Linux build has an issue that hangs the GitHub runner:

@twizmwazin, have you seen this before?

This might be a similar issue: https://bytemeta.vip/repo/joerick/cibuildwheel/issues/1189

I wonder if installing qemu on the runner will also fix this issue here?

sudo apt install qemu binfmt-support qemu-user-static

Yes, sorry I left that failing yesterday. The solution you proposed should work for ubuntu, I just pushed a commit that uses the docker/setup-qemu-action@v2 action, which should achieve the same result.

Awesome, looks great!
