Channel mapping 255 and Ambisonics mapping 2 and 3
Ambisonics is currently not available in opusfile. This PR is aiming to start implementing the remaining mappings for Opus and its tools.
The current state should enable encoding and decoding of Ambix / Higher-order ambisonics with the standard opus tools. Any reviews or suggestions are very welcome.
@chris-hld I am not a maintainer of opusfile, but I imagine the maintainers might like a cleaner commit history on this PR in order to consider it. I am happy to help test this
I took care of a last warning and completed the cleanup and documentation / commenting.
Everything related to mapping 3 should now also be guarded by OPUS_HAVE_OPUS_PROJECTION_H.
I am using and testing the modes of this PR daily and at least for me it's all working as expected.
Regarding the commit history, I completely agree. Feel free to squash on merge! If needed I can also rework the history and make it more compact.
