jFEX TOB bit shifted to agree with firmware

Sergi Rodriguez Bosca requested to merge serodrig/athena:reduced_TOBSv2 into master

This MR is meant to re-structure the TOB formation in the FPGA file and the TOB unpacking in the EDM classes to match the reduced TOB words used in the firmware. These changes only affect the internal structure of jFEX, in particular:

  • Small-R jets (jJ) from 32bits to 21bits
  • Large-R jets (jLJ) from 32bits to 23bits
  • MET (jXE) from 32bits to 31bits

Should be transparent for L1Topo, since they use unpacked information instead of the TOB words
