Follow-up from "Centralize the definition of make_jets to standard_jets.py"

The following discussion from !3242 (merged) should be addressed:

  I see there's lots of calls of SV = make_topo_2body_with_svtag() and TOPO = make_topo_2body()

  I would prefer having a _make_jet_tags() defined somewhere (standard_jets?) which can then be imported and we can replace these with a tag = _jet_tag_maker(tag_key='SV') or similar. This would then prevent things somehow getting slightly out of sync and is a bit neater.

  def _jet_tag_maker(tag_key):
      return {
          "TOPO": make_topo_2body,
          "SV": make_topo_2body_with_svtag,
      }[tag_key]
