Implement mp3/ogg/.. SoundFile decoding using JavaSound
Browse files Browse the repository at this point in the history 
This will break Android support to some extent, but fixes #32 by
switching to the much more well-supported (and 4x faster!) mp3spi,
closes #53 by adding support via vorbisspi, and also fixes #15 since 8
bit wav files are are now simply decoded through JavaSound.
