TST: Uncomment ramp fitting compares and clean up test_ramp_fitting.py

[pllim]

This PR uncomments ramp fitting test comparisons and clean up test_ramp_fitting.py to ease future maintenance. Not sure why they were commented back in #156

No need for RT.

Can we get a fast turnaround on this one so I can build #421 on it? 🙏

py3-xdist (macos-latest) will never run because it is picking up Python 3.14 (which this package disallows) and has been renamed to py313-xdist (macos-latest). This PR will need repo admin to override branch protection rule to merge, and then the admin has to update branch protection rule after merge.

pre-commit failure looks like some server hiccup. I can clear it later after initial review.

Thumbs up from the Roman side!
