[opus] encoder configuration

[Jean-Marc Valin]

Why do you want to force stereo? The encoder is designed such that if
there aren't enough bits to output stereo with enough quality, it
outputs mono instead (with better quality). Similarly,
OPUS_SET_BANDWIDTH() is used to tell the encoder to never go above a
certain bandwidth (e.g. there's no audio content there), but the encoder
will lower the bandwidth by itself to avoid outputing bad artefacts.
