Is there any reason you can't just use the generic multi-stream API,
i.e. opus_multistream_encoder_init() and give it the mapping you need?
This is how surround was originally done (in 1.0) and only got changed
when surround needed a more complex mapping and more data in the
encoder. If it turns out you need this kind of thing too, then yes we
would probably just want to extend the
opus_multistream_surround_encoder_*() calls since they already take a
