The pointer fp after the call to chromaprint_get_raw_fingerpoint() points to an
array of uint32_t whereas the current code assumed just a char stream. Thus
when writing the raw fingerprint, the output would be truncated by a factor of
4. This is fixed in the commit.
For reference the declaration of the function from chromaprint.h is:
int chromaprint_get_raw_fingerprint(ChromaprintContext *ctx, uint32_t
**fingerprint, int *size);
