FPGATrackSim: error handling for FPGA hits

This adds simple error handling (also as part of the CI) after observing exceptions coming from the FPGATrackSimHit::getLayer() at the inside-out algorithm, only when the reporting algorithm was enabled.

The exceptions were like the following:

FPGATrackSimHit::getLayer() called on a hit with invalid type: undefined
