Audio worklet support

[rfwatson]

Add support for bundling audio worklets.

Audio worklets are somewhat similar to web workers but have some different restrictions/challenges. This list isn't necessarily exhaustive, just what I remember from hacking with this previously:

1. Worklets are loaded using audioWorklet property instead of new Worker()
2. importScripts is not available in audio worklet scope
3. TextEncoder/TextDecoder not available in audio worklet scope, these are used by wasm-bindgen glue code so would probably have to be polyfilled

I'd be potentially interested in helping with this, but opening this issue for tracking purposes.
