Adding groomed jet radius and momentum balance for the soft drop groomed jet

[kawaho]

I am proposing to add the groomed jet radius and momentum balance in the return output of the exclusive_jets_softdrop_grooming function. These two are commonly studied jet substructure variables. The change is simple by basically calling

groomed_jet.structure_of<fastjet::contrib::SoftDrop>().delta_R();
groomed_jet.structure_of<fastjet::contrib::SoftDrop>(). symmetry();

and adding the results to the outputs. I am happy to make a pull request if this proposal is accepted.
