supplementalImps property
Provide a list of any necessary supplemental IMPs. You need supplemental
IMPs if the CPL that you're using for your input is in an incomplete IMP.
Specify either the supplemental IMP directories with a trailing slash or the
ASSETMAP.xml files. For example "s3://bucket/ov/",
"s3://bucket/vf2/ASSETMAP.xml". You don't need to specify the IMP that
contains your input CPL, because the service automatically detects it.
