BasicSDAudio Alpha Release and Demo

I have posted an alpha release of the BasicSDAudio library on GitHub! Check it out here. It is capable of 78125Hz stereo PWM audio outputs read from an uncompressed RAW file on an SD card. Psuedo 16bit playback should also be possible.

Also, here is a quick demo of the library running with my BabyBOOMER amplifier/buffer/filter prototype at 78125Hz, 8bit, mono output:

Testers and collaborators are welcome. Future improvements to the library include:

1. test stereo pseudo 16 bit playback
2. test higher output frequencies
3. auto called worker routine
4. efficiency improvements
5. multiple simultaneous file playback?
