Add TrackIsolation functor collection

Add the functor collection to replace TupleToolTrackIsolation in the FunTuple framework!

The following variables are added to the TrackIsolation collection:

• Number of tracks inside the cone;
• Summed P inside the cone;
• Summed PT inside the cone;
• Summed PX inside the cone;
• Summed PY inside the cone;
• Summed PZ inside the cone;
• Asymmetry variable for P between particle inside the cone and head;
• Asymmetry variable for PT between particle inside the cone and head;
• Asymmetry variable for PX between particle inside the cone and head;
• Asymmetry variable for PY between particle inside the cone and head;
• Asymmetry variable for PZ between particle inside the cone and head.
• Difference in eta angle between each track and head.
• Difference in phi angle between each track and head

TODO:

• Add DeltaEta and DeltaPhi to the collection
• Test in DV the collection
