Support PyO3 0.23

[ngoldbaum]

PyO3 0.23 is coming out soon (hopefully this week).

Supporting it should allow supporting the free-threaded build of Python 3.13 as well.

Here's the compiler error I get if I patch Cargo.toml to point at a local copy of the PyO3 repo with the main branch checked out:

It looks like almost all of the errors are related to the introduction of IntoPyObject and the removal of the gil-refs API so hopefully most of these will be straightforward to fix. I don't see anything related to the new Sync trait bound 0.23 adds to pyclasses, so that's good.

Thanks for the issue / analysis! Definitely appreciated.

I'm not sure I'll have any time to look into this for the next few weeks, so a PR (from anyone) is definitely welcome, otherwise hopefully will have a look at some point.

[ngoldbaum]

I'm planning to take a look at this.

[Julian]

That would be amazing, thanks Nathan!

[ngoldbaum]

I created #100, I'll follow up once 0.23 is finalized.

[ngoldbaum]

Fixed by #100
