Status of support for Python 3.13 and 3.14?

[cclauss]

README.md and pyproject.toml both state that Python support stops at Python 3.12.

GitHub Actions tests appear to be passing on Python 3.13. No tests are being run on Python 3.14 and Python 3.15 (in beta this week).

Is help needed to ensure compatibility with Python > v3.12?

Oh yeah, that would be great!

The README should have just be >= 3.7, instead of listing all versions explicitly.
