ENH: Switch to abi3 wheels

[larsoner]

@mgeier locally this worked:

$ python setup.py bdist_wheel
...
$ $ ls dist/
rtmixer-0.1.5-cp38-abi3-macosx_11_0_arm64.whl

and then I could install it, too.

Argh this will work for CPython only. Should we drop PyPy support or incorporate separate wheel build / logic (probably with scripts)? For example the audit command will vary depending on whether PyPy or CPython wheels are being built.

[mgeier]

I don't know if there are any potential PyPy users, but as a matter of principle I would like to keep providing PyPy wheels.

If it is too complicated, we can just keep generating wheels for all CPython versions as well. This seems to be what most projects are doing.

Maybe we should just wait until cibuildwheel supports what we want out-of-the-box?

[larsoner]

Okay it wasn't too bad -- I realized I could use build selector ORs with {} to get what we wanted without too much work. Then only the repair command needed to be changed / set based on whether CPython (and thus abi3 mode) was being used or not.

I'll merge this and cut 0.1.6 and we can see if it works! 🤞

Thanks a lot @larsoner, this works great!
