Add new particle retrieval tool for R3
Adding this tool lets the DF-level trigger matching run on run-3 style navgraphs. Right now the trigger API does not work for samples with the new navgraph so I've just hardcoded a list of triggers from @dzanzi for now. Longer term we'll fix the API and replace the hardcoded list with this.
I've checked these triggers and the matching results are exactly the same running on the AOD directly and running on the DAOD_PHYS produced. Unfortunately none of the multi-object triggers passed in the sample I had available though, but I'm confident that they should give the same results where they do pass.
