WIP: Implement QLflux-only running mechanism

Open Karel van de Plassche requested to merge karel/QLflux into main

Unfortunately this long-lived MR is not up-to-date anymore. The student that used this has left (I think @jon.citrin), and QuaLiKiz main has moved ahead. I'm rebasing, re-merging, and re-creating what is needed to continue.
