add Python 3.11 support

[MironBodewes]

It works fine for me with 3.10.6, but with python 3.11 it doesn't install. Edit: see exarkuns comment. I did change the Issue name.

This is expected. zfec is not yet tested against Python 3.11. This ticket could be retitled to "add Python 3.11 support" and someone could do the necessary CI setup, fix any issues, and make a release happen.

@MironBodewes It may interest you that zfex, a fork of zfec which I maintain, builds and installs with cpython 3.11.

Did a quick test on macOS (arm64) and Fedora 37 (x86_64). With Python 3.11, pip install zfec does install from the sdist package when a C compiler is available, so the issue must be that there are no wheel packages for Python 3.11?

I suppose can can do some things:

• Add Python 3.10 and Python 3.11 to the "test" workflow.
• Update cibuildwheel in the "build" workflow (they're now at 2.x releases, and we're pinned at 1.6.4) and until it magically makes py310 and py311 wheels. There's also a pypa/cibuildwheel@version action now, which simplifies things.

We could also look into abi3 wheels again (#49), now that cibuildwheel has support for it.
