No wheels for python 3.11

[davidbrochart]

Python 3.11 is out and already available on conda-forge, could we release y-py with wheels for it?

Would it be worth it to build for Python's stable ABI, so the built wheels are compatible across Python versions?
I'm not familiar with Rust (though I can help with Python stable ABI), but it should be possible with:

[dependencies.pyo3]
features = ["extension-module", "abi3-py37"]

(The resulting wheel should still be tested on all supported Python versions.)

Hey @encukou, I was checking out your abi3 proposal repository. How significant is the performance overhead that you mention?

[encukou]

You aren't likely to notice unless you're counting CPU instructions or optimizing for CPU cache at the Rust/Python boundary.
The biggest slowdown I know is that rather than accessing memory directly, “everything” is a function call. In particular, Py_INCREF is a C function call rather than C int increment.

My abi3 repo is a collection of notes, some of which are outdated now. The proposal was PEP 652 and official docs are at https://docs.python.org/3/c-api/stable.html. Let me know if I can clarify something.
