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.

The upstream URLs unfortunately aren't canonical, so let's have a
sources.nix which contains the release IDs used by the upstream sites to
associate a version of a particular package.
We're then going to create an updater script which should update the
sources.nix from there on.
