Add ability to specify a min / max pp range to reprocess

For partial processing, this becomes quite useful. For instance, we
could do a quick pass on all scores that "matter", or vice-versa.

I'm currently using this to process lower pp scores eagerly, as we don't
need to stop-the-world to update insignificant scores' PP values.
