Cannot pass objects into their parent objects without converting to a dict

[jettdc]

Currently this is invalid

created_stream = foundry_client.streams.Dataset.create(
    ...
    schema=StreamSchema(fields=[
        Field(name="value", schema=FieldSchema(nullable=False, dataType=StringType(type="string")))
    ])
)

you need to do

created_stream = foundry_client.streams.Dataset.create(
    ...
    schema=StreamSchema(fields=[
        Field(name="value", schema=FieldSchema(nullable=False, dataType=StringType(type="string")))
    ]).to_dict()
)

we should allow passing these types into functions that accept them, without converting to a dict

Currently the idea is that you instantiate the dicts directly rather than using the classes. For example:

created_stream = foundry_client.streams.Dataset.create(
    ...
    schema={"fields": [
        {"name": "value", "schema": {"nullable": False, "dataType": {"type":  "string"}}}
    ]
)

Supporting both options could definitely be something we implement in the future. We previously experimented with this option but decided to try just using dictionaries initially.

IMO, the tricky part with supporting classes is just ensuring the type definition is correct (so that pylance/mypy work as expected) and that code assist tools don't get confused by the union.
