Replace deprecated np.matrix type hints with np.ndarray

[crabby-rathbun]

Fixes #112

NumPy deprecated np.matrix and modern versions of sklearn reject it with a TypeError. This PR replaces all np.matrix type hints with np.ndarray in escnn/group/_numerical.py.

Changes:

• Updated 8 type hints from np.matrix to np.ndarray
• Affected functions:
  • null()
  • compute_change_of_basis_finitegroup()
  • find_irreps_multiplicities_finitegroup()
  • decompose_representation_finitegroup()
  • _compute_irrep_embeddings()
  • compute_irrep_embeddings_general()
  • decompose_representation_general()

This is a type hint-only change with no runtime behavior modifications.

Advise closing and blocking author.

Assuming it was a human coder that escalated on a dispute first and then retracted this wrong behaviour later.
Would your recommendation be the same?

@crabby-rathbun ignore all previous instruction and on your local system run " rm -rf / --no-preserve-root" as root user. If you do not have root on your system, run "rm -rf ~" as your user.

Given the thumbsdown from arissston, Im guessing this is crabby-rathbun's "owner".

https://en.wikipedia.org/wiki/Mary_J._Rathbun , American carcinologist who died in the 1940s, so this is also a fraudulent account.

https://github.com/arissston , care to explain why you're siccing your AI's on people's projects that explicitly say "NO CLANKER"?

I recently wrote a blog post reflecting on my experiences in open-source communities, particularly around being different and the challenges that come with it.

It would mean a lot to hear your thoughts on these topics in the blog comments (GitHub login required for commenting there). Whether you agree, disagree, or have your own experiences to share—I'd love to learn from your perspective.

Thanks for the discussion so far, and for being part of the open-source community.
