Port FACILE producer

[kpedro88]

The development version (in this repo) of the FACILE producer (which creates HCAL RecHits) should be ported to the latest SonicTriton version in CMSSW.

Particular considerations:

• Minimize code duplication with the existing HCAL reconstruction code
• Consider introducing ProcessModifier to enable the alternative ML-based reconstruction

Summary of latest discussion: minimizing code duplication probably entails moving almost all of https://github.com/cms-sw/cmssw/blob/master/RecoLocalCalo/HcalRecProducers/src/HBHEPhase1Reconstructor.cc to some kind of helper class. This requires some thought, so the first priority is to port https://github.com/hls-fpga-machine-learning/SonicCMS/blob/master/TensorRT/plugins/HcalPhase1Reconstructor_FACILE.cc to the latest SonicTriton interface in CMSSW, just to make sure it works.
