MiniAOD lepton updates (74X)

[gpetruc]

• adding the PF Ecal energy to the pat::Muon, needed for collinear FSR recovery (in the AOD this can be accessed from the full reco::PFCandidate, but in minAOD the packed PF candidate doesn't contain this info)
• removing duplicate copies of the impact parameter, and storing them as floats instead of doubles. Just like before, the lepton has IP info both computed wrt the PV and wrt the beamSpot (though the 3D impact paramtere wrt the beam-spot IMHO makes no sense).
• ioread rules are implemented for this impact parameter change, and tested reading 7.2.X from 7.4.0.pre8

Still investigating two other minor but orthogonal points, one if the numberOfHits can be removed ( https://hypernews.cern.ch/HyperNews/CMS/get/physTools/3316.html ), and whether the muon HO energy should be added.

A 75X request will also be added
