Simplifications and fixes to the MuonMatchVeloUT algorithm

To be merged once LHCb!1807 (merged) is resolved.

Including some modifications to the MuonMatchVeloUT algorithm:

1. Extrapolation to the muon chambers has been simplified.
2. How we define the search windows has changed.
3. Remove negligible corrections to the magnet focal plane parametrization.

Performance of the algorithm practically didn't change.

I'm also adding some classes and scripts to study the performance of the MuonMatchVeloUT algorithm. NTuple generation + performance studies.
