CI: add python wheel build in addition to source package

When using source distribution,
python package will be compiled during pip install.

Wheels make the end-to-end installation of Python packages faster:
- wheels are typically smaller in size than source distributions
- pip fetches a prebuilt wheel and avoids the intermediate step of building

So why cibuildwheel and manylinux?

See https://github.com/pypa/manylinux and https://github.com/pypa/cibuildwheel

The goal of the manylinux project is to provide a convenient way to distribute binary Python extensions as wheels on Linux

Skipping musllinux and auditwheel repair.
Skipping MacOS and Windows for now.
