Use correct oggz argument type in examples.

The examples using oggz must use oggz_package as the second argument to read_package for the callback to be acceptable by oggz_set_read_callback(). Adjust the method signature to use oggz_package and extract the required ogg_package members from this one to avoid compiler message like this:

fishsound-identify.c: In function ‘main’:
fishsound-identify.c:101:37: warning: passing argument 3 of ‘oggz_set_read_callback’ from incompatible pointer type [-Wincompatible-pointer-types]
