Update muon calibration to check for convergence of the fit

Summary

In the latest version of ctapipe were added new fields to the MuonEfficiencyContainer regarding validation of the fitting procedure.

What is the expected correct behavior?

Need to add proper processing of the new fields, particularly is_valid and parameters_at_limit in the MuonCalibrator class. In the case of a False value in is_valid or a True in parameters_at_limit, we should not store appropriate optical efficiency in our DB.
