test_tree3d fails with Python 3.13

[penguinpee]

I'm not exactly sure what the root cause of the failure is. But it looks likely to be Python 3.13 (currently 3.13.0rc2), which will be the Python version shipped with Fedora 41 in a few weeks time. With Python 3.12 the same test succeeds.

Hello! It's due to matplotlib fixing the axes auto-scaling in line collections in 3.9.1.
Could you try if #1131 builds without issues?

[penguinpee]

Yes, that fixes the failing test. Thank you.

NeuroM 4.0.3 should do the trick. Please let me know if you still have issues.
