WebRTC <> HWI App

[KayBeSee]

In order for HWI to work in a browser setting, there needs to be some sort of companion app that is able to run and access USB ports to support HWI communication.

I think the most straightforward way to do this is via a small electron companion app that simply connects to the browser window running Lily via WebRTC and relays communication that way.

This relies on #64 being finished.
