This adds the ability to prefetch the cacheline required to answer a
rankquery.I'm not quite sure I did it correctly though...
In my evals (https://curiouscoding.nl/posts/quadrank/#evals), the data points (the black plusses) get better when going from
fortostreamwith prefetch for the largest configuration (flat+64bit blocks), but the 3 other configurations get worse, so maybe I am fixing the wrong cachelines? not sure.My wrapping code is here: https://github.com/RagnarGrootKoerkamp/quadrank/blob/master/src/genedex.rs
