There were inconsistencies in the way the ID Trigger sequences were configured. These changes partly address this to tidy the configuration code somewhat. As part of this is a fix to the naming convention in the beamspot chains, together with the implementation of a test beamspot chain in the LS2 menu. This includes a renaming of the beamspot chain in the pp_run3 menu, to conform to the established naming conventin from Run 2, that has been agreed with Menu coordination.
