Auto-generate enum.StrEnum classes from cafPdmPythonGenerator for every
caf::AppEnum-backed scriptable field, deduplicated by C++ AppEnum type.
Generated PdmObject attributes and method arguments now reference the
typed enum (e.g. self.depth_type: DepthType = DepthType.MEASURED_DEPTH)
instead of bare str. Member names are sanitized against Python keywords
and identifier rules (None -> None_, R-G -> R_G).
Existing scripts that pass plain strings keep working because StrEnum
members are strings; the wire format is unchanged.
Bumps python_requires to >=3.11 (StrEnum). Adds an Enum branch in
PdmObjectBase.__convert_to_grpc_value so future IntEnum use is also
handled.
