feat: Add a Millepede result reader

[goblirsc]

Add a MillePedeResultReader that can parse the result files generated by Millepede.

Adds a reader utility to parse the output file produced by the pede alignment fitter.
Will return the results in a vector of parameter-level outcomes.

No attempt is made to translate the abstract parameters / labels back to surfaces and transforms - this is intended to be done by the caller (or in the Examples framework), taking into account their specific alignment logic.

Also add a unit test and python bindings.

Should go in after #5954
