Improve some L1 Event/Timeslice related printouts

Branched out from !1009 (merged) to refocus it. Principle green light was given when these commits were still there, but maybe somebody should still review it quickly.

• In CA Trk finder, replace std print for max triplet limit w/ LOG(debug)
• Fix + improve stats per evt/TS/run for debug output in L1GlobalTrackFinder evt mode
  • Fix calculation of integrated values of STS hist and Tracks over the TS
  • Add nb MUCH/TRD/TOF hits per event in L1GlobalTracker debug printout
  • Add runtime per event in end of run printout
• In main L1 class, convert printout per TS/Evt to LOG, set to debug as default
