Added RaceStatusEncoder.

Refactored RaceStatusDecoder to be more consistent with other decoders - it now has a getMessage() function.
Added BoatStatus encoder and decoder - the RaceStatus encoder and decoder uses this for BoatStatuses. The BoatStatus encoder doesn't implement the MessageEncoder interface as BoatStatus is not a proper message type (doesn't inherit from AC35Data).
Added remaining cases to EncoderFactory, but commented them out.
BoatStatus now uses BoatStatusEnum instead of a byte.
Added some comments to RaceStatus, and it uses enums instead of bytes.
MockOutput logs a warning if a RaceStatus cannot be encoded.
Added a BoatStatusDecoderTest.
Updated RaceStatusDecoder to use new encoders/decoders.
