Kamodo was removed (dependency conflicts)

[sapols]

I recently migrated the PyHC environment to Python 3.12.

Kamodo was removed because it was the root cause of dependency conflicts:

• pandas<2 — too old, must be updated (opened this issue about it)
• numpy<2 — wasn't a dealbreaker but SPEC 0 says it's time to support NumPy 2 (this issue was opened)

It's also been an open issue for a while that Kamodo isn't installable via pip/conda. We've been installing Kamodo specially from its GitHub URL, but that's a bad look for a core package. This would be a good time to fix at least the pip install to get Kamodo re-added the normal way.

If we fix Kamodo's outdated dependencies, close #20

And if we fix Kamodo's pip install such that it joins the rest of the pipeline requirements, close #5
