Spring cleaning of Jet/Etmiss derivation framework
This MR mostly gets rid of old smart slimming lists not used anymore for analyses.
Tagging the FTAG experts to make sure that they are ok with those modifications as well as some of those were used in the past by FTAG @duperrin @thuffman @vdao @biliu
Tagging also @jcatmore as this will slighly change the content of PHYS. The R = 1.0 truth soft-drop jets (four-vectors + five other variables) are now added to PHYS. This is the jet collection that Jet/Etmiss will use for precision and replace the LCTopo jets. We're just waiting for the final UFO config. If prefered, I can undo the changes so that those truth jets are not automatically written out for the moment until we replace them.
