reduce hlt2 rate for jet+gamma line

The trigger rate of JetGamma line is quite large, so we would like to reduce it's rate, by implementing tighter jet/gamma pT cuts, and the invariant mass cut (from 10 GeV to 50 GeV).

The old trigger rates are:
Hlt2QEE_WZRareJetGammaDDDecision Incl: 0.000 +/- 0.000 kHz, Excl: 0.000 +/- 0.000 kHz
Hlt2QEE_WZRareJetGammaDecision Incl: 1.700 +/- 0.291 kHz, Excl: 0.100 +/- 0.071 kHz
Hlt2QEE_WZRareJetGammaLLDecision Incl: 0.200 +/- 0.100 kHz, Excl: 0.000 +/- 0.000 kHz

And after the trigger rate turning, the new rates are,
Hlt2QEE_WZRareJetGammaDDDecision Incl: 0.000 +/- 0.000 kHz, Excl: 0.000 +/- 0.000 kHz
Hlt2QEE_WZRareJetGammaDecision Incl: 0.350 +/- 0.132 kHz, Excl: 0.000 +/- 0.000 kHz
Hlt2QEE_WZRareJetGammaLLDecision Incl: 0.100 +/- 0.071 kHz, Excl: 0.000 +/- 0.000 kHz

The rate of JetGamma line is reduced by a factor of 4.8. These rates are tested with 20k events, as
