Update for B2pphh

Changes merged here affect B->ppKK, B->pppipi and B->ppKpi remain commented due to problematic bandwidth

patch generated by https://gitlab.cern.ch/lhcb/Moore/-/jobs/37993339

last round, the rate estimated by a old script, so it is underestimated.

Add functor:

F.MIN(F.MINIPCHI2(pvs)) > daughter_mipchi2_min
F.BPVIPCHI2(pvs) < bpvipchi2_max
F.BPVLTIME(pvs) > ltime_min
F.MAXDOCACUT(amaxdoca4h)

Now the rate

pipi: 285 Hz
KK: 148 Hz
Kpi: 285 Hz

bandwidth for all three lines (40K events, 100K samples are running)

0.125 GB/s 

efficiency based on CanRecoChildren

pipi: 0.222 +/- 0.035
KK: 0.368 +/- 0.036
Kpi： 0.239 +/- 0.034

UPDATE: Add tight PID on proton

F.PID_P<3 & F.PID_P - F.PID_K > -5.

Efficiency (not CanRecoChildren)

B->pppipi: (5.5+/-0.7)% -> (5.4+/-0.7)%
B->ppKpi: (7.3+/-0.8)% ->(7.1+/-0.8)%
B->ppKK: (8.2+/-0.9)% -> (8.0+/-0.8)%

Rate:

B->pppipi: 260 Hz
B->ppKpi: 160 Hz
B->ppKK:100 Hz

bandwith for all three channels:

0.0342 GB/s
