[WIP] Removed bounds everywhere!

[yaelbh]

Summary

In #190 it was suggested to remove bounds from all over the code. We haven't decided whether it's a good idea, and until now it's been done only for T1. I've decided to promote the topic by creating this PR, where bounds is aggressively removed from all the experiments, without checking the consequences.

Details and comments

Things that remain to be done (I'll need help from experiment owners for some of them):

• Handle the 8 failing tests (details below).
• Update the tutorials: The only tutorial that's directly using the bounds parameter is RB. The other tutorials need to rerun as well because there can be small changes in results, but I don't expect issues.
• Run Sphinx - expected to work without issues.

More details about the failing tests:

• RB tests fail because of the caching - need to regenerate the data.
• test_run_single_curve_fail (in test_curve_fit.py) verifies correct reaction when fit fails by fitting with infeasible boundaries. Another way of failing the fit is now required.
• Some calibration tests fail, I don't know why.
