Add a config to output first-, second-, or third-order ambisonics

Currently incomplete, as second- and third-order output will not correctly
handle B-Format input buffers. A standalone up-sampler will be needed, similar
to the high-quality decoder.

Also, output is ACN ordering with SN3D normalization. A config option will
eventually be provided to change this if desired.
