Decode/Convert from 3D Reality audio (MPEG-H 3D Audio) to 7.1

[Salem874]

With Spatial Audio in music expanding, it would be good if dBMC could read/convert from Spatial Audio formats like MPEG-H 3D Audio (commonly known as 3D Reality Audio) to other multichannel audio like traditional 7.1/5.1 AAC/FLAC etc.

Dolby Atmos would be nice as well, but I'm assuming this becomes difficult for licensing reasons?
