Fork with AudioWorklet implementation

[miker2049]

Hi, I really like this library, and I have made an attempt to reuse a lot of its bits and create a version that uses AudioWorkletProcessor rather than the very deprecated ScriptProcessorNode. Can be found here.

I need to work on completely copying the api here, with the duration features and events, but it stays pretty close right now otherwise. Most of the original index.js is now bundled into a registerProcessor for the AudioWorkletGlobalScope, and a second interface class MIDIPlayer handles all the messy communication with the worklet, as well as instantiating itself from an async static builder.

Some improvements otherwise include dynamically loading the timidity.cfg file on building the instance, and simply requiring that the pat folders are found in the same place. Also, a built in build system with rollup is now included.

I am not sure there is PR interest/how active this library is, and this is a pretty big set of changes. But let me know! It is right now working pretty well.

this is pretty interesting @miker2049. I tried to install your fork but I'm running into errors
