Kamodo removed until it supports Python>=3.12

[sapols]

In this commit I removed Kamodo from pyhc-core entirely (it's also been removed from the PyHC Environment which now runs Python 3.12). We'll add it back once they support Python>=3.12.

These were related issues:

• Kamodo import fails with Python 3.12 #9
• Does pip install kamodo miss anything? #3
