2017-12-10: Preliminary MOGG Support. As long as the stream is unencrypted, this should be fine.
            This will also work on unconventional 5 channel Vorbis streams but some sound cards might not like it.
            TODO (Eventually): Add decryption for encrypted MOGG types (Rock Band, etc.)
