When querying across two points in time this describes the change in
the finding between the two points: CHANGED, UNCHANGED, ADDED, or
REMOVED. Findings can not be deleted, so REMOVED implies that the
finding at timestamp does not match the filter specified, but it did
at timestamp - compare_duration. If there was no compare_duration
supplied in the request the state change will be: UNUSED
