Major refactoring to the SBND fhicl workflow

[fjnicolas]

From conversation with @henrylay97: our current "standard" fhicl workflow has become messy and would need a major refactoring in the near future. This issue is just to remind ourselves to work on that after the about to start workshop production and before the next mayor production.

A non complete list of things to do:

• Turn SCE on as default (Make default fcls use SCE config #287)
• What data products do we want/need to keep after G4?
  • It may be different for the different workflows we currently have available (legacy gen+g4, rockbox, recently added scrubs, recently added Wire Cell...)
  • We'd probably need to differenciate what's needed for production level vs user level
  • Revisit what's drop by the lite fhicls
• Standarize a workflow for WC?
• Better organize the fhicl directories foe each stage
  • E.g. standard/g4 currently has more than 100 fhicls. It makes complicated to easily find the relevant/essential fhicls. Maybe add more subdirectories for each specific set of fhicls (eg recomb_variations, timelife_variations, etc)
• Invert dependencies in genie+cosmics gen fhicl (Invert dependencies of genie+cosmics fcl files #201)
• Update wiki page
• [to be continued]

To be discussed in AI meetings.

One thing I have already thought to add to this when we do this is try and move things that are high level reco that currently reside in cafmaker into reco2 (things like PID tools, CRUMBS, MCS etc).

Just dumping things in this issue as I find them... Can we add gibuu to the name of this fcl?

Just to say, I have slowly started on some reorganisation: https://github.com/SBNSoftware/sbndcode/tree/dbrailsf_noicefclmate/sbndcode

It's being slowly discussed in the sbnd-software slack
