py-audioread: updated to 3.0.0

3.0.0
Drop support for Python 2 and older versions of Python 3. The library now \ 
requires Python 3.6+. Increase default block size in FFmpegAudioFile to get \ 
slightly faster file reading. Cache backends for faster lookup (thanks to \ 
@bmcfee). Audio file classes now inherit from a common base AudioFile class.
