The promised updater, which feeds sources.nix and should help updating all the aqbanking libraries at the same time. I was very reluctant to write the updater entirely in Nix as I've done a while ago for Chromium, because this would involve ugly hacks to do so. That's why I've done a more conservative approach here, only using nix-instantiate to get the contents of the current sources.nix.
