21.2 DAOD PHYSLITE MET Patches
This MR sets up a custom MET for DAOD PHYSLITE. It requires rebuilding charged PFlow objects from the AOD, then constructing a MET that uses all the analysis objects that are written to PHYSLITE. We get containers out with different names.
Along the way made a tweak to a PFlow module to use a function rather than an action-on-import module.
