#235 Incorrect endian used when converting to caf on OSX
On the latest OSX build, converting to caf seems to always output a big-endian irrespective of the --endian setting. If I then look at the outputted caf in Quicktime, or in my own sound loading code, the file is actually big endian.
sox test.wav --endian little test.caf -V -V

Yes, the sndfile format handler currently ignores any endian setting completely.
