SUSYTools: Automatically set data type for the PhotonEfficiencyCorrectionTool
The PhotonEfficiencyCorrectionTool needs to have the data type (AtlFast or FullSim) manually set. The previous PhotonID recommendations for Rel22 only considered FullSim SFs, but now SFs are available for AtlFast as well (only for Run2, see the EGammaRecommendationsR22 twiki).
The PhotonEfficiencyCorrectionTool initialization in ST only considered setting the data type to FullSim, so when using AF3 samples incorrect SFs and uncertainties were obtained.
This MR sets the MC sample type automatically for Run2 samples only, leaving the behaviour for Run3 samples unchanged.
