Description
PSyclone doesn't currently have any builtins that perform a minimisation/maximisation reduction on a local field.
There are currently 3 PSyKAl-lite routines which exist because of this issue; those are:
- `invoke_real32_local_field_min_max`
- `invoke_real64_local_field_min_max`
- `invoke_int32_local_field_min_max`
which are found in LFRic core `components/science/source/psy/sci_psykal_builtin_light_mod`. These are all called by `components/science/source/algorithm/sci_field_minmax_alg_mod.f90` in LFRic core.
I was unable to find any reference to a specific PSyclone issue.

Research direction
Start by reading the three PSyKAl-lite routines in components/science/source/psy/sci_psykal_builtin_light_mod and their callers in components/science/source/algorithm/sci_field_minmax_alg_mod.f90. Trace how PSyclone represents existing builtins and determine what is needed for local-field minimisation and maximisation reductions. Done means PSyclone supports these reductions without the three LFRic-specific routines.
