added decoders for avg wind, course wind and mark rounding

-refactered networking test file structure
-added average wind decoder
-added course wind decoder
-added mark rounding decoder
-updated boat location decoder
-added true wind direction to the boatLocationMessage class
-added true wind direction to raceVisionByteEncoder method for boat location
