Adding trimmed UFO jets to JETMX derivations

This MR adds UFO CHS and CSSK trimmed jets to JETM3, JETM4 and JETM6. These jet collections are needed to do further studies to understand the impact of constituent-level pile-up suppression and grooming algorithms on jets. Functions are added to be able to call UFO CHS jet building easily in derivations and to be able to also add these in trains.

Furthermore the smart slimming list was added for ungroomed UFO CHS jets.

A problem with small-R jets (R = 0.4) was found in JETM3 that was introduced with the last MR. These collections are now added back in and R = 0.2 and R = 0.6 jets are added again to the smart slimming list as was done previously.

Tagging @jveatch because he was doing similar modifications earlier for UFO CSSK jets.
