Better NPM worklet handling

[spessasus]

Is your feature request related to a problem? Please describe.
Currently, the NPM users have to manually copy over the worklet_processor.min.js every update. This is not good, and there's no way to tell bundlers to import it from node_modules

Is your feature related to the sound library or the app/website?

Something better that the current implementation. I'm not good with npm or bundlers, so help would be appreciated!
