Description
The following deep operators I believe exist to calculate the operations within halo cells and be marked as clean after -
* `invoke_deep_X_times_Y`
* `invoke_deep_X_divideby_Y`
* `invoke_deep_shift_mass`
found in LFRic apps `science/gungho/source/psy/psykal_lite_transport_mod`. These are all called by `science/gungho/source/algorithm/transport/common/transport_runtime_alg_mod.x90`.
I could not find a relevant PSyclone issue for this. There was an attempt to avoid the need for the PSyKAl-lite code in [LFRic #4302](https://code.metoffice.gov.uk/trac/lfric/ticket/4302), however, this was closed.

Research direction
Start by inspecting the three named deep operators in science/gungho/source/psy/psykal_lite_transport_mod and their calls from science/gungho/source/algorithm/transport/common/transport_runtime_alg_mod.x90. Determine how these halo-cell operations are represented and what marks them clean; done means the operators are handled consistently without relying on the closed LFRic attempt.
