Support Python (rclpy) #4
Description
I would like the full ICEY API to be supported in Python as well. Python/rclpy differs from rclcpp mainly because it already has partial support for async/await. For instance, service calls and TF lookups return promises.
However, rclpy's support for async/await is incomplete since callbacks are not awaited (ros2/message_filters#123).
Therefore, supporting Python requires completing the existing partial support first.
