ATR-22298 Isolated, high pT trigger, CPU Reduction Changes

I am introducing a new pT cut for the Isolated Track Trigger, that introduces a significant CPU reduction for the trigger. In addition, I have changed the naming scheme of cumulative (icummedium) isolation to aggravated (iaggrmeduim) as the previous acronym icum was unintentionally vulgar.
