[PD] soundfiler features

[Lucas Cordiviola]

Good.

I think is better to use the data-chunk header, cuz broken sound files are far less common than files with metadata.

And broken sound files can be fixed, (copy audio and paste to a new file).

[soundfile_info] assumes that everything after the (1st) "data" chunk is
audio data.
this is obviously not true if you have other chunks (cue, ...) coming
after the audio.
i talked to thomas, and it seems that the behaviour was actually
intentional, meant to correctly handle truncated soundfile files (that
would be shorted than indicated in the data-chunk header)
as a side-effect, it would erroneously handle soundfiles that are longer
than indicated in the data-chunk header.

i fixed this in iemlib's git repository[1].
i'll try to talk thomas into doing a proper release via deken.
