Modularise sim WF

* offers
    * explicitly select modules and detectors with --modules and
      --readout-detectors flags, respectively
    * better overview and managing of dependencies

* introduce a SimulationWorkflow class
    * automatically resolves dependencies
    * introduce posiibility to identify a task by a stage and detector
      source such as ("RECO", "TPC")
      to make dependencies more clear based on what is actually going on
      NOTE: Still room for improvement
          * could do this for as many tasks as possible, atm only DIGI,
            RECO and MATCH tasks use this feature
          * task names could automatically be built from that
    * remove explicit TF suffix from task names and add automatically
    * does not add tasks for inactive detectors
    * possibility to compose source strings such as "ITS,TPC,TPC-TRD"
      automatically from proposed sources --> non-existent sources would
      be trimmed

* some tasks adjusted to their minimal dependencies

* small adjustments in o2dpg_qc_finalization_workflow.py to comply with
  <taskname>_<timeframe> format of tasknames per timeframe
