use fixed fork of JetToolbox
Fixes errors:
python encountered the error: <type ‘exceptions.ImportError’> cannot import name hepTopTagPFJetsCHS
Illegal parameter found in configuration. The parameter is named: 'addTagInfos'
NB, also updated CMSSW branch TreeMaker:AddJetAxis1_942
to fix a bug. Now it actually runs (at least on a random Summer16 MC file I checked).
