MC request using splitSim to study different decay modes with converted photons

Requires the use of

$APPCONFIG/options/Gauss/SplitSim-GammaConversionFilter.py https://gitlab.cern.ch/lhcb-datapkg/AppConfig/-/blob/v3-patches/options/Gauss/SplitSim-GammaConversionFilter.py and $APPCONFIG/options/Gauss/GammaConversionFilter_ExtendZ.py https://gitlab.cern.ch/lhcb-datapkg/AppConfig/-/blob/v3-patches/options/Gauss/GammaConversionFilter_ExtendZ.py?ref_type=heads

FYI : the production will pass through the RD group , CC'ed @elsmith , @abiolchi , @rihender

THe production is across different channels :

• Bs-> Phi gamma
• B0 -> K* gamma
• Lb-> L gamma
• B+ -> K+ pi0 ( to verify we could gain something in pi0 -> gg )

The SplitSim with the conversion at Z < 2400 has a retention rate of 20% in Gauss, so i scaled 2M generated events by a factor 4. All samples to be generated DST since it would be useful to study also some 'restripping' dedicated to those decays.

As i am new to the request, which field has to be added to the yaml to specify this is SplitSim and the additional AppConfig has to configured @adavis ?

Requires lbmcsubmit!66 (merged)
