Generalise ParticleMassMonitor to non alignment usage
View options
ParticleMassMonitor (https://gitlab.cern.ch/lhcb/Rec/-/blob/master/Phys/ParticleMaker/src/ParticleMassMonitor.cpp) was changed in !3469 (merged) (@miruizdi) to add new plots to be used for SciFi alignment. There are some variables like particles names hard-coded (only names for decays D^0 \to K \pi or J/ \psi \to \mu \mu).
The same monitor but appliying a mass constraint using DTF also exists (https://gitlab.cern.ch/lhcb/Rec/-/blob/master/Phys/ParticleMaker/src/ParticleMassDTFMonitor.cpp), but now the two monitors have different features.
Some tests like Moore!2373 (merged) (still WIP) also use ParticleMassMonitor.
