Summary: dsd to pcm support

Initial Comment:
Sebastian Gesemann wrote a c based code to convert dsd (dsdiff) to pcm at 
24/352.4. I contacted Sebastian and request to be able to use and distribute 
the code he said sure. I can provide the exchange between us as needed. I then 
had a friend modify the code to parse the dsd data and make the same conversion 
without the header information. Can we add dsd to pcm support directly to SoX 
with this code? I can provide the code as needed.
Thanks
JR

Message:
Sebastian Gesemann release his DSD2PCM code under the simplified DSB
license here: https://code.google.com/p/dsd2pcm/

The license probably simplifies using his code. The first stage of his code
converts the raw DSD stream to 352.8 kHz PCM 32-bits floating-point and
this is probably the only part which should be used.

The most used fileformats which contain DSD streams are DSDIFF (see
http://www.sonicstudio.com/pdf/dsd/DSDIFF_1.5_Spec.pdf) which has the .dff
extension from Philips and the simpler DSF fileformat from Sony (see
http://www.dsd-format.sony.net/data/DSFFileFormatSpec_E.zip) which has a
.dsf extension.
