Bug 782091 - Add multichannel Opus test files. r=derf

This doesn't do any verification of the output, just checks
that we load multichannel files and playback completes.

These are public-domain test files created by Tim and Monty
last year. They're not great audio quality, the idea is just
to verify correct speaker mapping.
