Open Drone ID Specification updated to 0.59.0

The Open Drone ID Specification is updated to 0.59.0 to improve the ability to parse/process the messages. Primarily, we took most of the fields that were split across byte boundaries and divided them into even byte boundaries (8, 16, 32 bits, etc). This makes it far easier to process. To make a bit of space in the Location Message, we moved the operator location to a separate message.
