WebMIDIKit announcement

Hey,
I just wanted to say that I've written a small library called WebMIDIKit
that implements the WebMIDI API in Swift.

https://github.com/adamnemecek/WebMIDIKit

It's to replace the terrible CoreMIDI API.

It's not like 100% compliant yet (e.g. it doesn't throw exceptions on
invalid messages) but it's mostly there.
