Python >=3.12 Compatibility

[LiamOS]

With python 3.12, SafeConfigParser has been removed; deprecated since 3.2.
Fixing this issue locally didn't resolve this for me, so I guess the incompatibility goes slightly deeper than one import.

As an aside, if it would be possible to release the next version of gegede on PyPi that would be much appreciated. 🙂
