added decoder test for boatlocation

-refactered networking test file structure
-boatlocationdecoder now makes a boatlocation message with its data
-boatlocationmessage sequence number changed to an int
-racevisionbyteencode changed device type to just be a byte
-fixed the short conversion in racevisionbyteencode
-added boatlocation decoder test
