Update complex sequence references
The complex sequence reference files were not updated concurrently with the default reference files, leading to failures of the efficiency test in the full CI pipeline (#283 (closed)). This MR fixes this issue.
The actual reason for the performance change is attributed to !648 (merged) , see the discussion at !710 (comment 5007788) . See also related issues #283 (closed) and #284 (closed)
