Since the dataset must be accessible from the CI runner, the best
solution is probably to commit a small dataset containing only the
required cycles. It's included in this commit, and can be generated by
extract-from-h5.py using the same cycles list as the one used by
vfc_test_h5.cpp.
Moreover, the probes exported by vfc_test_h5.cpp are now 0-padded, which
will result in a better sorting in the results.
