Include sTGC Efficiencies from HV data

This MR includes a basic, preliminary framework to include HV efficiencies in the sTGC digitization. The efficiencies are read from a .dat file and come from the latest data from completed sTGC sectors. These are the efficiencies of the wire to hold HV which allows them to induce charge and create digits on the sTGC strips, wire and pads.

The final framework of this kind of efficiency should be handled by databases and not .dat files, but should still be applied at the digitization level.
