This MR mostly gets rid of old smart slimming lists not used anymore for analyses.
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.
