Edge case fixes for jFEX Sim
This MR fixes various edge cases in the jFEX simulation:
- fixed integer overflows in jXE calculation
- fixed jEM seed condition eliminating both seed candidates in case of equal ET instead of choosing one over the other (wrong comparison operator was used in direction requiring a candidate to have greater or equal energy than a neighboring seed)
- added LAr saturation bit propagation in jFEX fwdEM algorithm (purely to improve fw/sim comparison for monitoring; the resulting jEM saturation bit is in practice ignored by L1Topo)
