Getting boat locations from race simulator & bug fixes

- Boat locations that are generated by the simulator are sent to the client as they happen
- Fixed heading and lat/lon encoding
- Fixed a bug where the header wasn't included in the sent byte stream
- Fixed the format of data as it's sent to the client.
- Data is now sent using a channel
- Removed tests that don't work with channels
