update readme/setup.py: python <3.13 because of audioop

[afeistel]

audioop got removed in Python 3.13, so import hata fails on 3.13;
on 3.12, seems to, at least, import fine

[afeistel]

I assume later audioop should probably be replaced with something else but for now this at least clarifies it doesn't support 3.13

Python 3.12 is not fully supported yet either, because of the new f-string syntax is not fully implemented in expression boundary parsing. I know its not mentioned in the setup file, but the dependencies have it mentioned.

Sadly pip does not care about supported python versions (& operation systems) and lets the installation pass.

So setting < 3.12 would match the requirements better. <3

okay then that also covers SyntaxWarnings for now, since those start with 3.12

(the ones about \_ and \:, mostly)

pip does not care about supported python versions

I'm using uv, and that thing cares quite a lot about Python versions, so at least there it matters

Yes. I once fixed those issues, but seems like some escaped if you got them.
At that time, I researched the SyntaxWarning in the "whats new", and it turned out that it is already a thing since 3.6, but some bug(?) prevented them being displayed.

I will try to go through the SyntaxWarning again, thanks for finding them.
