✨ Add support for deque objects and children in jsonable_encoder

[cranium]

Currently, deques with pydantic models as children are not encoded by jsonable_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"}]
