[QHC-697] Adding Calibration checkpoints

[GuillermoAbadLopez]

TODOs of PR:

• Implement the main idea of the checkpoints algorithm
• Implement Comparison of fidelity in output dictionary and values in node.check_value
• Test this, with concrete mock notebooks
• Write quick docstrings
• Cover functionality with tests
• Write better docstrings

Also some other checks:

• Make sure is backwards compatible, if no checkpoints are passed
• Make sure weird cases indeed work correctly, like green checkpoints after red ones...

---

NEW TODOs:

• Do test of full flow run_automaitc_calibration, with the permutations of V and X, for both checkpoints
• End the unit test of diagnose with the checkpoints 👌

Remember to add a test of the diagnose method as I believe is not covered rn

[IsaacLA12]

After careful review, testing it with edge cases, hand to hand with @GuillermoAbadLopez, I believe it is good to go.
Leaving my aprove but adding software testing is needed to pass codecov and also test it on HW when available.
