Adding collision mode for ComTimeRec
We sometimes want to run cosmic reco on collision events for the purpose of long-lived particle analysis. In those cases, the timing of the detector is the same as it is in collision mode (for the trigger, at least), even though cosmic reconstruction is configured. This allows an additional mode for the ComTimeRec algorithm, wherein it doesn't try to find the cosmic track record in simulation, but assumes that we are running something collision-like.
