Support for newer version of python

[jpmorr]

I can't see too many problems associated with running on newer versions of python such as 3.12 or 3.13. Is it possible to update so it's pip installable?

pip install from a python3.13 venv is working on my side

sudo apt install libcgal-dev libeigen3-dev
pip install pygalmesh

worked for me. with Python 3.12.6.
