[PROBLEM] MPD does'nt read Multi tag on DSF DSD etc.. files

[Nutul]

There is also this PR from @Nutul which may or may not have some bearing on the issue.

Hi Tim,

the changes in the PR, unfortunately, will only help moOde find its way through the correct address of the id3 tag in the DSD file (and retrieve the album art, as that was the reason of it); MPD itself won't get any advantage, of course.

Although the problem might be similar... as the zend id3 tag library assumes the tag is at the very beginning of the audio file, which is not always (actually, never...) true for dsd/dsf files; maybe the decoders used in MPD are not correctly handling such files, don't know, just wandering in the wild here...

BTW, I wrote the fix as there was a guy complaining about the album art not being extracted... he sent over a couple of DSDs, which I no longer have... it would be interesting to have a further look into them...
