New feature: event sphericity calculation in FemtoDream framework

  • added Event sphericity histogram
  • added sphericity calculation (with matrix elements taken from EPJC72:2124)
  • added sphericity event cut code in producer tasks
  • deleted femtoDreamProducerTaskWithCascades.cxx due to incompatibility with sphericity calculation code (in consultation with @gmantzar: cascade building will be reintegrated in the normal producer task, making the ProducerWithCascades obsolete. PR is under preparation)
  • added event cut on minimal sphericity in femtoDreamPairTaskTrackTrack.cxx

Added code for shpericity calculation.
Sphericity matrix is taken from: EPJC72:2124
Deleted cascade producer for compatibility reasons with sphericity calculation.
Sphericity calculation: added MinSphericity and SphericityPtmin configurables as event cuts
Sphericity calculation: added MinSphericity and SphericityPtmin configurables as event cuts
