This is a minimal implementation in order to keep moving forward.
For simplicity I've copied over the old implementation verbatim. Note
that this is beatmap*set* based randomisation, which means that when
panels are split up by difficulty, it is still randomising by set (with
the difficulty choice being left up to the user recommendation system).
I think this is what we want, but if it isn't, any changes can come
later.
