Draft: add benchmark for RICH IRT

close #81

• add RICH benchmark in benchmarks/rich
  • main script: run_irt.sh called by CI in process stage
    • runs scripts/simulate.py, an npsim wrapper specific for RICH tests
    • runs scripts/draw_histos.C, to check some raw results from scripts/simulate.py
    • runs gaudirun.py options/irt.py to run new Juggler algorithm IRTAlgorithm
    • eventually we should add some analysis script after gaudirun.py (start a new MR)
  • CI jobs:
    • 2 runs for each RICH, one for acceptance test and another for yield vs. momentum
    • artifacts from raw hits output to results/rich
    • more tests and artifacts to be added as we continue to develop IRT code
• new CI process jobs will fail until IRTAlgorithm is merged in Juggler
  • see pipeline https://eicweb.phy.anl.gov/EIC/benchmarks/reconstruction_benchmarks/-/pipelines/23625 where IRTAlgorithm step is disabled (artifacts results/rich)
