Wheels for Python 3.13

[egorsmkv]

Py 3.13 is already a stable release so it would be nice to have wheels on PyPI as well.

Yet I have the following error:

error: Failed to prepare distributions
  Caused by: Failed to fetch wheel: sphn==0.1.4
  Caused by: Build backend failed to build wheel through `build_wheel` (exit status: 1)

Running `maturin pep517 build-wheel -i /home/yehor/.cache/uv/builds-v0/.tmpkMiaZV/bin/python --compatibility off`

The cause here is this - error: the configured Python interpreter version (3.13) is newer than PyO3's maximum supported version (3.12) - as I understand.

Seems like PyO3 should be upgrade to 0.22 here - https://github.com/kyutai-labs/sphn/blob/main/Cargo.toml#L21C1-L21C16

I've just updated to PyO3 0.23 in #8 so hopefully we should be good with python 3.13. I'll have a look at building the new wheels at some point.
