Migrate from ScriptProcessorNode to AudioWorklet #9
Description
After many years of ScriptProcessorNode being officially deprecated without any actual replacement, AudioWorklet is finally live in Chrome 66 and Opera.
This should help with playback problems

Still an open Bugzilla ticket for Firefox support. Will want to feature-detect and allow falling back to the old system. Progress on other browser support unknown (At a glance, it doesn't seem to be coming to Edge soon).
Also need to revisit if these primitives are being used correctly for JSModPlayer. Good discussion about the difficulties of dynamic audio here: WebAudio/web-audio-api#1322
