Most changes are renaming. 'Station' idents are unclear wrt expect values "CS001" vs "CS001HBA0".
    Parset.cc has a clear "translation" point. Added 2 TODOs, as renaming these two functions is too invasive for this task.
  Add option to restrict cobalt nodes to those that receive streams from ant fields in the obs.
    Default off, because as JD mentioned, this may exclude nodes that are needed for computing only.
