Add build wheels, tarball and deploy to pypi

[t20100]

This PR adds a github actions "workflow" to automate the generation of wheels thanks to cibuildwheel and the upload to pypi thanks to gh-action-pypi-publish.
This workflow is triggered when a release is published in github.
I already did the set-up to use pypi's trusted publishers. As it is you have to publish a github release on a tag starting with v to trigger the workflow and click on a button approve the upload to pypi. This can be more automated (e.g., upload when a tag is pushed to the repo but it makes it more sensitive to errors).

It build the source distribution and wheels for Python 3.7 to 3.12 for:

• MacOS: universal2, i.e., x86_64 and arm64
• Windows: x86_64
• Linux: x86_64, aarch64 and ppc64le

Tests are run only on "native" architecture (i.e., x86_64).
It could also build for 32bits architecture on Windows and Linux but dependencies like scipy are not available for this architecture so it has little interest.

Limitations:

• No python3.12 wheel for ppc64le: This can be done but not for manylinux2014 as I didn't managed to build a wheel of numpy for python3.12 on ppc64le (yet?).
• No tests on Windows, if I recall it was failing on compiling bslz4_to_sparse, so the solution could be to generate wheels for this project too.
• No tests for emulated architectures.

I tested the deployment on test.pypi.org
