This commit adds a driver for the Blokas Pisound audio/MIDI HAT based on the Linux sources. Currently this requires a patch to Circle to allow the Pi's I2S audio device to operate in slave mode. The Pisound only works at 48000Hz, 96000Hz, and 192000Hz. The Pisound is automatically detected by the startup code; the user only has to enable I2S audio output. MIDI output and recording functionality is not supported. Closes #42.
