id3 added format detection logic to Tag::read_from_path, so the same API now works for mp3/wav/aiff. the only thing needed was a version bump and some test cases.
the existing a.wav asset had no tag chunk in it, which caused the existing test case to fail (the other assets have empty or trivial tags). so a.wav and a.aif both have empty tag chunks to start with.
