Subject: Add preliminary support for 7.1.4 output modes
I don't know how different sound APIs handle 7.1.4 ("Atmos" or "Auro3D")
output, but currently it simply specifies the additional channels with the
height channel labels. This isn't likely how it works for a virtualized channel
bed, for playing over other with-height configurations (7.1.2, 5.1.4, etc), but
this should be an okay start.
