[PD] [sfinfo~]

[Lucas Cordiviola]

@Oliver

The only problem I know with [soundfile_info] is that it counts as 
samples any metadata in the file. Is not common to find metadata in wav 
files but there might be some.

It would be really nice if [soundfiler] just extracts n of samples only 
by reading the header.

@Dan:

Oliver's patch shows that [soundfiler] does not just "read the header".
