* Drop support for Python 3.7.
* Build Windows wheels on GHA.
* Add support for Python 3.13.
* Enable multi-phase module initialization (PEP 489) for all
supported Python versions. See this "how-to" doc for
rationale and steps:
https://docs.python.org/3.13/howto/isolating-extensions.html
* Make the hookable extension type heap-allocated for Python >=
3.9. Likewise, see the doc above for rationale and steps.
For Python < 3.9, the hookable extension type continues to be
allocated statically, even though the module itself is
allocated dynamically.
