oakkitten 863cef5e64 Tests: use time machine to “pin” Anki dependencies
Packages anki and aqt do not pin their requirements,
which breaks anki <= 2.1.49 because of protobuf major version bump.

While it's possible to use requirements.txt as constraints,
it might not be the best idea:
  * requirements.txt can’t be used as constraints
    without some careful sed’ding to remove hashes and extras;
  * its location changes between versions;
  * you can’t get this file for a pre-release version of Anki
    since these don't get git tags;
  * it’s rarely updated anyway and hence won’t reliably
    produce the environment that actual Anki uses.

So use a pypi-timemachine, which prevents pip from using packages
that were uploaded after a specified date.
While the code is a tad complex, it feels slightly less hacky,
and is likely to be producing more accurate environments.
