+eat up samples quicker than the server provides them and we end up with an empty buffer.
+To fix this, the mp3 logic can insert/delete some samples to modify the speed of playback.
+If our buffers are filling up too fast (presumably due to a quick sample clock on the other side)
+we will increase our playout speed; if our buffers empty too quickly, we will decrease it a bit.
+Unfortunately, adding or deleting samples isn't very good for the audio quality. If you
+want better quality, turn this off and/or feel free to implement a better algorithm.

+then output that value on the I2S port. The net result is that the average analog value on the 
+I2S data pin corresponds to the value of the MP3 sample we're trying to output. Needless to
