message: speedup of the response simulation for high dEdx particles
  Needed for magnetic monopoles
  Changes:
  * void AliTPC::MakeSector
  * do electron transport for group of electrons
  * for low Q<150 el group size=1 => simulation as always
  * for higher Q (monopoles) group size Q/100
  * Using clion auto-indentation in affected routine
