[Rivet] Method for accessing particles from FastJets projection

My template abuse aside, having them the same makes it "just work" when my
muscle memory goes to the fastjet::PseudoJet interface, whereas now I get a
compiler error, and have to look up the difference on Doxygen (I know I'm
being whiny here, but rivet is so fun to use, that when there are friction
points they're much more glaring than other HEP software).

This is fine, I only pitched it my way because I was planning on doing
something similar in another analysis framework, and wanted to see if I was
in unknown waters :).
