Fixed muon pf iso reprise

TauID: it is pretty much correct. The only difference w.r.t. bacon is that our isolation (line 105) returns a boolean whereas in bacon you get the actual deposit. Currently our implementation results in a tighter selection

MuonIsolation: Josh's changes for-ported. That should reflect what done during the hgg synchronization. But then why was that ok for the htt one?.. I suggest to cross check this before merging
