New release with support for Python 3.12

[mbehrle]

Hi Andrew,

as Python 3.12 is scheduled as default Python version in Debian pywebdav will be removed from testing soonish. As at least #42 seems to be solved and the last release 0.10.0 dates from on Dec 31, 2022 could you please release pywebdav in the current state?

Thank you
Mathias

Hi, I've just merged a couple of cleanups and released it, hopefully it works for you!
