The checksum values for most wrapper versions are hard-coded into the action. These known checksum values are first used for validation: only if none of the known values work do we download checksums. Previously, we blindly downloaded all of the checksum values in this case: we now only download the checksums for versions that are not in our "known" set. Fixes #171
