Merged requested to merge tadej/athena:fix-jets into 23.0
Workaround jet CA reordering by introducing CA flattening:
- only for parallel sequences (we could limit ourselves even more)
- also add
- there's one place for legacy where the CA is still unmerged, but I did not want to refactor the config more
I did not test the output but derivations now run without complaints.
