Add templated mergers

Add templated SOACollectionMerger and VectorOfObjectsMerger, to make merging of SOACollection-based classes and std::vector<Object> collections easier.

Thanks, this seems useful indeed. I think we had some implementation of this but not generic (for instance https://gitlab.cern.ch/lhcb/Rec/-/blob/master/Tr/TrackUtils/src/TracksVPMerger.cpp).

@ahennequ I tested this yesterday with the TrackListMerger in Rec!3001 (closed) and observe a segfault, as soon as it tries to add the second container (and the segfault happens in copy_back). The code looks very simple and it essentially copy-paste from some older code, so I was wondering if anything changed in the implementation of the SOACollection.
