Update JpsiXsec trigger

Mengzhen Wang requested to merge psixsec_triggerTuning into bandq_development

Tuning of Jpsi, psi2S Xsec lines:

Tighter the PID and PT cuts. Same value as latest decision of offline selection.

Looser mass window to benefit cfit.

Rate variation tested using the suggested snippet script, with 100k hlt1 filtered MC events as input. Total rate gets decreased.

Jpsi: 1950 Hz -> 1510 Hz (195, 151 events among 100k input passed the selection)

Psi2S: 350 Hz -> 400 Hz (35, 40 events among 100k input passed the selection)
