First commit for MC request
DecFile for the decay chain [D*(2010)+ -> (D0 -> (K*(892)- -> (KS0 -> pi+ pi-) pi-) mu+ nu_mu) pi+]CC, which is required to implement a new HLT2 line. There is already a DecFile for this decay chain (https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/-/blob/v30r113/dkfiles/Dst_D0pi,Kstmunu=TightCut.dec), but the changes I made are:
- I required the KS0 to decay into pi+pi-
- I removed the TightCuts, requiring instead DecProdCuts
