Add B->Dh dec files with K3pi amplitude models
Adds the DecFiles:
Bu_D0K,Kpipipi=DecProdCut,AmpGen.dec: # EventType: 12165042 Bu_D0K,piKpipi=DecProdCut,AmpGen.dec: # EventType: 12165043 Bu_D0pi,Kpipipi=DecProdCut,AmpGen.dec:# EventType: 12165052 Bu_D0pi,piKpipi=DecProdCut,AmpGen.dec:# EventType: 12165053
For studying efficiencies for CPV studies in these modes.
