beets: 1.4.9 -> unstable-2020-12-22

The maintainer has stopped cutting releases[1]. Since the last release,
1.4.9, includes a dependency that is filled with hate speech[2] it's all
the more reason to package the unstable version and eliminate that
requirement.

Moreover a number of fixes, improvements, and features have landed
since.
