ValueError: year 0 is out of range

Proposed fix

Similar to https://github.com/thebigmunch/google-music-proto/issues/6, ValueError should be gracefully handled.

Changed the label to enhancement, since it's not technically a bug to error out on invalid input. But audio-metadata should definitely handle this case gracefully as well as ParserError.
