Fixes to Foresee sampler and validation + add Fluka reader + add faser-specific particle gun (not changed yet)

Add scripts to generator events from Foresee and a sampler to read these in to the DIF + config for this.  Add ability to read HepMC input events.  Add Validation alg

Update digitisation to have realistic normalisation and baseline.  Update reco with --isMC arg to run on digitised MC

Fix missing trigger scintillators in reco

See merge request faser/calypso!206

Fix missing trigger scintillators, add some counters to waveform reco, cleanup excessive INFO output

Add cable mapping DB for waveform digitizer

See merge request faser/calypso!205

Update code to make full use of the Gaudi property, change data format to store aligment constants. Update python scripts to make use of the changes.

Use a FASER-appropriate module frame

See merge request faser/calypso!204

Modify the tracker database generation tool so it can read an external input. This removes the requirement of hard-coding alignment constants and recompiling after each alignment iteration. The currently chosen format to be read as input is a json file.
