(DAOD LLP1) Add lowest unprescaled multijet+ht triggers
This MR adds lowest unprescaled multijet+HT triggers to LLP1. The included multijet+HT triggers is an 2023+2022 OR of the lowest unprescaled jet triggers ("Small-R, "H_T" according to the twiki https://twiki.cern.ch/twiki/bin/view/Atlas/LowestUnprescaled).
Using data23_13p6TeV.00454129.physics_Main.merge.AOD.f1360_m2179._lb0756._0003.1 containing 7381 events (with SMK 3223/ HLT prescale 6599 / L1 prescale 7676 / "Physics_pp_run3_v1") the per-event size difference increases because more events (~6.8%) pass trigger skim (4690 total events including multijet+HT, 4389 total events in main). The size difference between the two files is 27 MB, output files in /eos/user/l/labruce/LLP1_multijetHT_trigger/.
