Harmonized interface between calibration output and fair input

[chrisroadmap]

Standardise the column names in the calibrated_constrained_parameters.csv file in a way that is logical input for fair to pick up calibrations with maximum abstraction/minimum user interaction.

fair 2.2.0 in its f.override_defaults() method does this. Just need to link up the parameter dump to these explicit names.
