New inclusive BDT line for Xic0 -> pK-K-pi+ (Turbo++)

MVA-based inclusive Xic0 -> pK-K-pi+ hlt2 line

prerequisites:

• This new line is using "InclOmegacCombiner" combiner and "InclOmegacPromptChild_x" input (x=pi,K,p) developed by Ao Xu included in merge request 516, so it is not included in changes here (although I can add it if necessary)
• look-up table ("InclXic0ToPpKmKmPip.txt" ) - already requested to merge into ParamFiles package - see ParamFiles merge request 2

documentation:

• First presentation
• Second presentation
• JIRA task: LBHLT-417

additional info:

• preferred working point - BDT > 0.27 (can be tightened in case of bandwidth requirements, see bellow) - measured CPU is 2.78 ms / event
• required persistency - PersistReco
• possible working points (BDT cuts) and their rates [Hz] - measured with 50k Hlt1 accepted data and Hlt1Global Rate 110kHz:
  • BDT > 0.25 -> rate 61.6 ± 11.6
  • BDT > 0.27 -> rate 41.80 ± 9.59
  • BDT > 0.28 -> rate 30.80 ± 8.23
  • BDT > 0.29 -> rate 26.40 ± 7.62
  • BDT > 0.30 -> rate 22.00 ± 6.96
• efficiencies [%] of the new BDT line with threshold 0.27 (existing cut based line) for the different sources of Xic0:
  • 26104080: prompt Xic0 -> 1.07 ± 0.11 (0.14 ± 0.04)
  • 16875030: Xic0 from Xi_b- -> 3.79 ± 0.18 (0.45 ± 0.06)
  • 26165850: Xic0 from Xi_cc+ -> 1.14 ± 0.11 (0.04 ± 0.02)
