omas can't deepcopy certain sub-ODSs

[jmcclena]

example:

ods= ODS()
ods['equilibrium.time_slice.0'] = ODS()
ods2 = ODS()
ods2['equilibrium.time_slice'] = copy.deepcopy(ods['equilibrium.time_slice'])

returns the following error:

Error in "OMFIT command box #2" at line  8
    ods2['equilibrium.time_slice'] = copy.deepcopy(ods['equilibrium.time_slice'])
LookupError: Not a valid IMAS 3.36.0 location: equilibrium.time_slice
                                                           ^^^^^^^^^^
Did you mean: time_slice, time, ids_properties, vacuum_toroidal_field, grids_ggd, ...

@jmcclena the error is not on the deep-copy end, but at the time of insertion. This will work:

ods= ODS()
ods['equilibrium.time_slice.0'] = ODS()

ods2 = ODS()
ods2['equilibrium.time_slice'] = ODS()
ods2['equilibrium.time_slice'].update(copy.deepcopy(ods['equilibrium.time_slice']))

I agree this is not ideal, and I can look more closely why the error happens.
