81c9e2e6d0 alac: split element parsing into a separate function
This will make multi-channel implementation simpler.
Based partially on a patch by Andrew D'Addesio <modchipv12@gmail.com>.

73dc0db486 alac: output in planar sample format
Avoids unneeded interleaving and allows for reusing the AVFrame output buffer
as the internal buffer for 24-bit and 32-bit sample size.
