Fix endianness bug when generating fingerprint in big endian machines

Fixes https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1093700

The script

import acoustid

example_file = '/usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga'
print(acoustid.fingerprint_file(example_file)[1].decode())

generates wrong fingerprint in big endian machines.

This PR fixes this issue.

I'm pretty sure byteswaps are handled in audioread correctly.

Please reopen if this really is still an issue and I will have a more in-depth look.

it's worth mentioning that this code does not appear to have made it into an audioread release yet
