Download testdata

The (binary) test data:
    raw sfxc output, known-good MS, known-good IDI file, support files (*.vix, *.lis)

should not live in the code repository. They're now in a bzip2'ed tarfile
that will be downloadable from `archive.jive.nl`.

On test execution does a simple check to see if the data has already been
downloaded and if not, downloads & inflates & extracts in the appropriate
place.
