Add cibuildwheel

[severinsimmler]

This PR introduces cibuildwheel to build wheels for different platforms (i.e. Windows, Linux and macOS).

I'll add a GitHub Actions workflow in the next PR where this can actually be used, but you can try it out locally by running:

$ cibuildwheel --platform linux

(Assuming you have installed build dependencies with poetry install --only build --no-root)

Note that specifying macos or windows as platform only works on that operating system, but linux works on all three, as long as Docker/Podman is installed.

This will produce 8 wheels:

This raised:

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'cfloat'?

[severinsimmler]

We have to skip these because of numpy/numpy#24703 (comment)
and there were also problems with win32 builds (some files NumPy relies on were unavailable iirc).

This looks great. Thank you!

Might take me a week or two to check everything.

Thanks. This all looks good.
