Add uncertainties for main parameters.

[Sparks29032]

Need tests for warnings and each parameter separately (including baselineslope).

Need special handling for squeeze and func[x/y/xy] morph parameters.

Case where all parameters have uncertainties:

Case where certain parameters cause the Hessian to turn singular:

Tests and documentation updated. Ready to merge after review.

[Sparks29032]

Oops, previous one I ran only one of the tests I thought would be affected... fixed now.

Loosened tolerance for checking numerics match. New algorithms and updates to old ones can cause some deviation (e.g. works on one of our tests on PR workflows but not others).

[sbillinge]

looks great. One inline comment.

[sbillinge]

are you retaining these lines for some reason? If yes, state the reason and when they can be removed, and if not, then just remove them.

[Sparks29032]

@sbillinge Removed the stray comment.

Since pre-commit isn't working on here (we will address by #301 hopefully), this screenshot is just to confirm it is passing it locally.
