Plain HTML/JS audio recording demo using vmsg

A simple HTML5/JS demo that uses vmsg to record mp3 audio in the browser. Works on both mobile - including Safari 11 - and desktop.

As opposed to earlier JavaScript mp3 encoding solutions, vmsg uses a faster WebAssembly version of the latest LAME mp3 encoder (3.100 from october 2017).

All the vmsg demos are React based so I thought I'd do a plain HTML/JS one. I've taken great care to make the demo as easy to use on mobile and desktop.
