DCA: 20-bit XLL storage resolution is not implemented.

[susnux]

Summary of the bug:
Trying to encode a dtshd track I have got a lot of warnings about not implemented 20-bit XLL storage resolution.
Tested also the latest static build, same result, see next section.

How to reproduce:

% ffmpeg -i "dtshd testfile.mka" -c flac output.mka
