Liquidsoap for Docker

Assuming you have a folder /music with a liquidsoap script file in it:

docker run --link some-icecast -v /music:/music:ro phasecorex/liquidsoap /music/script.liq

This has been heavily modified from infiniteproject/liquidsoap:

• Added support for opus, flac, and m4a/aac files
• Much smaller image size (215MB instead of 1.66GB)
• Runs as non-root user
  • You can set environment variable PUID to whatever user ID you want Liquidsoap to run as. Defaults to 1000.
  • You can also set PGID to a group ID you want Liquidsoap to run as. If you don't, it defaults to whatever the UID is set to.
• Timezone support
  • You can set environment variable TZ to a timezone (e.g. TZ=America/Detroit) so that Liquidsoap logs are in your timezone.

Feedback appreciated!
