Asktell/aposmm reg test with vocs + other changes

[jlnav]

Note several things:

• We're still doing numpy back and forth for aposmm
• But aposmm's x and f need to be "mapped" to core,edge,energy for vocs, since vocs also decides history
• So mapping is needed, but not np_to_list_dicts mapping.
• unmap_numpy_array is useful. the reverse was added, map_numpy_array.
• the mapping of "sim_id" is special. if _id comes in, we swap it with sim_id. If sim_id goes out, we obviously want sim_id to come back
• Simplification of list_dicts_to_np was more possible once we treated only the mapping fields as base truth if its in sync with the input data
