* freedb: Remove unused code and set client name to whipper.
The removed functions depend on other classes of python-audio-tools,
but aren't needed here.
* cddb-py: replace with newer freedb implementation
The last release of cddb-py was 15 years ago. The freedb code taken
from python-audio-tools speaks protocol version 6 (Unicode) and is
compatible to both Python 2 and 3.
* freedb: Don't allow the pedantic CI test to fail
