ScriptProcessorNode deprecation warnings

[gherkins]

Some FX-Types rely on the deprecated ScriptProcessorNode and will produce the following console warning

The ScriptProcessorNode is deprecated. Use AudioWorkletNode instead.

Happens for example with FX-Types Chorus, Phaser, Tremolo & WahWah

I'd like to see node implementations moved to audio worklets (the modern way of implementing custom audio nodes as I understand).

@felixniemeyer Check out my fork for worklet implementation and type definitions: https://github.com/devindavies/tuna

You're right that they should be converted! Adding that to my decently sized todo list. :)

Fun fact; I believe this warning started appearing quite early in Web Audio's lifecycle (definitely before 2015, at least, probably more like 2013), but the unofficial messaging was "don't worry, we're not removing the script processor anytime soon", so we never bothered back then. Future me wish we'd taken the time.
