FPGATrackSim: Implemented use of a layer map to make slice dependent layer assignments

Added code to read a layer map from a JSON file and use it to assign layers after binning. The layer map is set in the python with hooks to set it as a command line flag "Trigger.FPGATrackSim.GenScan.layerMapFile=path/lyrmap.json". The default behavior is unchanged. If the layer map is set then its used.

Yeah, the layer assignment for a hit might be different for different slices, so which hit is in which layer has to be communicated through the "road" object. Luckily, when I looked at the combinatorial engine in the tracking code, this seems to be the case.

It does leave open the possibility of misunderstanding, but at this point removing "layer" from the hits is hard.
