Description
Structured outputs currently only support Pydantic models (which are very useful), but is presently missing support for simple Enums, and requires redundant wrapping into a Pydantic model.
I want to be able to perform queries such as:
class SomeEnum(Enum):
SomeType: 'SomeType',
AnotherType: 'AnotherType'
response = ollama.chat(
model=...,
messages=...,
format=SomeEnum)

Research direction
Start by tracing how ollama.chat handles the format argument and how the existing Pydantic structured-output path is implemented. Add support for passing a simple Python Enum directly, then verify that structured responses are constrained to the Enum values and that the existing Pydantic behavior remains unchanged.
