Authentication Broke

As of 2021-04-02 authentication appears broken:

panic: login: unexpected result 400 Bad Request:
{"message":"Invalid username and/or password","errorCode":0,"errorString":"AUTH_INVALID_USERNAME_PASSWORD"}

Looking at the browser, three extra fields are set that appear to be SSO related:

• OZ_DT
• OZ_SG
• OZ_TC

It seems resilient to replays, just ripping the values from the login request from the web client doesn't work. Curiously, pianobar still works. Perhaps we can implement the partner login flow to obtain a token instead?

So the bad news is I seem to have fubar'd my gstreamer install because I can't get mousiki to compile on windows anymore. But, logging in via the legacy route appears to give an auth token that's valid for the REST API. I'm going to merge this with a half-fix for #9 that shells out to FFmpeg to convert tracks to PCM that we can play with https://github.com/faiface/beep. It's not perfect though, details in #9.
