Modify TOPQ4, remove MET selection and replace with Dexter jet selection
See: https://its.cern.ch/jira/browse/TOPQDERIV-110
The goal of this request is to remove the current MET selection in the TOPQ4 skimming (as this was based on a variable that should not be used for physics analysis) and instead replace it with a selection requiring a Dexter-tagged jet.
