Doc error for audioio.WaveFile example #851
Description
The documentation for playing a file from flash in:
https://github.com/adafruit/circuitpython/blob/master/shared-bindings/audioio/AudioOut.c#L83
needs to be updated to be consistent with
https://github.com/adafruit/circuitpython/blob/master/shared-bindings/audioio/WaveFile.c#L61
the first one gives an error while the second one works but it is the first one that is seen in ReadTheDocs:
http://circuitpython.readthedocs.io/en/latest/shared-bindings/audioio/AudioOut.html
