jFEX jet algorithms and MET container name fixes
This algorithm fixes a bug in the jFEX jet algorithm. The current local maximum finder assumes you have signed deltaPhi values, which were not returned from the helper function. That was fixed, and the absolute value explicitly added where needed.
During the debugging, it was also realized that because the tile energy is taken from the Run 2 container with a noise cut already applied, the way we derive noise thresholds is not really sensible. Given that during the startup, we have to share noise cuts with Run 2 anyway, it probably makes sense to not apply tile noise cuts. Those were removed for the jet algorithm anyway.
In addition, there is a minor fix to the MET Aux container name.
