Merge branch 'jcidvida/my-changes' into 'master'

Dec files to study the potential of the Muon System to find a very long-lived LLP decaying to a pair of tau leptons. The taus decay hadronically with tauola. This benchmark is selected according to the CMS paper https://arxiv.org/pdf/2107.04838.pdf The pipeline fails because of the event type. I've followed the convention to find the event type. From previous decfiles I wrote, I think this should be fine, please let me know if not. I'm also copying other interested parts in case they have comments @lohenry @lshchuts @cvazquez
