Returns a rospy.Subscriber.
Local message packages are not required. Subscribes as AnyMsg, creates message class dynamically from connection info, and deserializes message before providing to handler.
Supplemented with .get_message_class(), .get_message_definition(), .get_message_type_hash(), and .get_qoses().
The supplementary .get_message_xyz() methods should only be invoked after at least one message has been received from the topic, as they get populated from live connection metadata.
