Release 0.2.0

This version incorporates a great deal of new discoveries about how to obtain track metadata, playlists, beat grids, cue lists, and track waveform data from players, as well as new interpretations of bytes within the status and beat packets. The protocol analysis document has grown substantially, and major new features have been implemented in Beat Link and Beat Link Trigger based on these breakthroughs. A hearty thanks to Austin Wright for sharing the details that brought us to this next level!
