v0.3.12 (#408)

### New
- AudioWorklet replaces the deprecated ScriptProcessorNode (when available) in p5.SoundRecorder, p5.Amplitude, and p5.SoundFile, as part of @oshoham's GSoC project https://github.com/processing/p5.js/blob/master/developer_docs/project_wrapups/orenshoham_gsoc_2019.md
#369
#373
- p5 library compiled with webpack so it looks a little different and we had to remove comments that were tripping up YUIDoc here in the p5.js repo

### Fixes
- p5.SoundFile: stop() won't stop a soundfile loop https://github.com/processing/p5.js-sound/issues/401
- p5.SoundFile: addCue() not triggering function calls https://github.com/processing/p5.js-sound/issues/371
- p5.SoundFile: jump() only called if soundfile is playing #404
- p5.SoundFile: save() bugfix #406
- remove bad console call (#378)
