Unify L1 simulation sequence data_rerun and MC paths: ATR-23072
Lots of code duplication in MC and data setup for L1 simulation sequence. Replace with a single function.
Identical results with the following tests:
test_trig_mc_v1Dev.py
test_trig_mc_v1Dev_L1Only_build.py
test_trig_mc_v1Dev_L1Only_phase1_build.py
test_trig_data_v1Dev_rerun.py
test_trig_data_v1Dev_rerunL1Only_build.py
test_trig_data_v1Dev_rerunL1Only_phase1_build.py
