Updated EZAudio to master version 0.0.3 with new extensions, updates, and bug fixes.

Changelog:
- Changing EZAudioPlot and EZAudioPlotGL to scroll for the EZPlotTypeRolling instead of wiping the screen clean when hitting the end
- Allowed EZMicrophone EZOutput to have custom AudioStreamBasicDescription setters
- Fixed bug in EZAudioFile's getWaveformData function where it was not exiting after sending back cached waveform data (rereading from the audio file)
- Added stereo support for EZMicrophone, EZAudioFile, EZRecorder, and EZOutput
- Added more memory cleanup for EZAudioFile
- Added adjustable rolling length for EZAudioPlot and EZAudioPlotGL so those rolling graphs can now range from 128 to 8192 whereas before it was fixed at 1024
- Added adjustable resolution for waveform data coming from the EZAudioFile so output from the getWaveformDataWithCompletionBlock: function can literally be of any size. Try 128 for a low resolution waveform or 8192 for a much higher resolution waveform.
- Added quick fix for EZOutput to properly route stereo data coming from a circular buffer datasource. Next version (0.0.4) needs to add EZConverter to allow quick conversions between non-interleaved and interleaved formats.
