Partially handle ambisonics in alffplay
This is currently really only applicable to Opus-encoded files. It assumes AmbiX (SN3D normalization, ACN ordering) and only comes into play when the channel layout is blank. FFmpeg/libavcodec doesn't have a way to detect B-Format input or what normalization and ordering it uses. Note in particular .amb files do not play correctly (libavcodec seems to apply a default channel layout for 4-channel wav-type files, regardless of its channel mask value).
