TypeError: Type is not JSON serializable: datetime.time

Reproduce: Try to send a `datetime.time` object to CrateDB.

With the new orjson we pass datetime objects to our custom [json_encoder](https://github.com/crate/crate-python/blob/6ec9995f3ede0f392c24ef712d7d2dadd8d99093/src/crate/client/http.py#L93), `datetime.time` is not handled.
