Currently, deques with pydantic models as children are not encoded byjsonable_encoder.

dq=deque([Model(test="test")])jsonable_encoder(dq)# => [Model(test="test")]

This PR addresses this by including deque along with the other iterable types (set, generator, etc)

dq=deque([Model(test="test")])jsonable_encoder(dq)# => [{"test": "test"}]
