install python 3.12

I'll check if there's any breaking with python 3.13 if not we can extend the support to include it

install python 3.12

I have it, but I don't want to change the system version of python.

That would be great, thank you!

Python 3.13 support is still tricky, see: #198

Not keeping this issue open as it will resolve itself as dependencies get updated, just use Python 3.12 in the meantime.
