add option to check if event passes mufilter selection

Mark/flag the events passing the mufilter selection:

pT> 3000 and eta < 2.8

In this way, we can keep track of the events from the NON 'mufilt' samples also passing this selection. Scope of the flag: we will be able to veto/reweight these events when combining the mufilt and non-mufilt DSIDs.

Add a branch to the ntuples to define if an event passes the mufilt selection or not.
Add a property to the CxAODMaker_FlavourTagging as well.
