Bug#903718: gplaycli currently unusable in stable/backport/testing/unstable

[Andres Salomon]

As you discovered, the version in experimental works. Unfortunately,
googleplay-api (which gplaycli uses) has a strict dependency on
newer versions of protobuf, which are available only in experimental.
So we've been stuck waiting on protobuf 3.6 to transition to
unstable.  It is not the only package stuck waiting on protobuf to
transition.  See https://bugs.debian.org/901015 for transition status.
