Redefine the gain as gain*rcalib in the LUT Coder

This change is necessary to implement the new EM fine grain bit
algorithm for HF.
Add an array shift to HcalTriggerPrimitiveAlgo

Added a shift, hf_lumi_shift, to correct for lumi bits stuck on the
front of the array that are used by lumi but not trigger. We correct
these based on the given rctlsb.

Also add a MAX_OUTPUT = 1023 test to analyzeHFV1 to prevent overflow.
