Changes to tau smart slimming and TAUP's extra variables list
- removing variables that we no longer use/that are repeated/that are broken
- removing links to containers that we don't save variables for
- adding variables needed to check modelling of RNN tau algorithms
- changing default selection to RNN WPs instead of BDT ones in TauCommon
@martindl @cgrefe @lfiorini for information @egramsta so we can discuss the impact of these changes on other derivations before merging it in
