CalibrationDataInterface: adding verbose to cout message in CalibrationDataInterfaceROOT
We observe in the EasyJet package a number of warnings not useful to the user. One of these is an information given by the CalibrationDataInterfaceROOT, which outputs messages like:
CalibrationDataInterfaceROOT::checkWeightScaleFactors: cross-checking scale factors for objects GN2v00LegacyWP/AntiKt4EMPFlowJets/Continuous/Light/default_SF and GN2v00LegacyWP/AntiKt4EMPFlowJets/Continuous/Light/default_Eff
In this MR, I apply to the relevant section the same verbosity flag as similar debug messages in the code. This doesn't affect the output nor the usage of the tool.
