Update JAMS output to JAMS v0.2.0. We now (for the first time?!) write actual JAMS schema-compliant output when possible, though it isn't possible for many types of plugin. The output for all tested combinations of transforms is valid JSON even where it isn't schema-compliant.

# If JAMS is installed, we can report on whether the outputs are valid
# JAMS schema files or not -- unfortunately we can't comply with the
# schema for most real plugins, so we can only make indicative reports
# for most. This is such a limited test that we make it optional; it's
# a bit much to expect everyone to have JAMS installed just for
# this. Also the JAMS verifier doesn't currently always work for me
# (e.g. it doesn't seem to work correctly with Python 3 at the moment)
# so let's not make this fatal either.
