State of this branch: basically working with worklet, but...

1. createScriptProcessor is used in tuna.js anyways, so it will need
   updating in order to actually do away with the warnings,
   and avoid future bit rot.
   Theodeus/tuna#88
   https://stackoverflow.com/questions/68007500/how-to-migrate-to-audioworkletnode-from-scriptprocessornode
   I could send a PR, or perhaps switch to a different effects chain.
2. String bending doesn't work
3. Maybe there's an error that can occur where fret is undefined?
   Note implicit assignment at play: (@fret)->
   Note there's GuitarStringProcessor::play and GuitarString::play
