Adding python wheels for the package and for the kernels

[michaelfeil]

With this PR, you can click Release, and create a tag that starts of with wheels*, e.g. wheels-0.0.1. The wheel is created for each torch major and cuda version, I would recommend getting the right build from the right matrix.

Background: The CudaExtensions takes decent time in CI to build, I prefer to pin some version from the github release, over a clone + pip install -e .

Pipeline should be roughly reusable. I built it partially from scratch, partially from Autoawq. Its running under MIT Licence.

Cheers

This can be merged FYI

Thanks so much for this PR, it looks really helpful.

Two requests:

1. Do you know if there's a way to test the release build before merging?
2. Can you please squash the commits into one?

2. For squashing - could this be done in Github UI by you / merging?
3. It could be possible to run the unit tests upon installation. Is this required?

[DanFu09]

I don't think I can squash it, since it's a PR from your branch. I'm not an expert in github's online interfaces though :)

For the tests - I mean can we run the unit tests just once before merging them in to validate. (if you can run them and share a screenshot of the results that is good too)
