Subject: Add LUPS reporting and fix glaring oversight

The GLFW window rendering loop used to dispatch the compute shaders was
restricted to 60 FPS. I did not notice this because I never actually
measured the computed lattice updates per seconds in addition to trying
to push the GPU to its limits. Turns out the lattice sizes I commonly
use can be updated 500 times per second comfortably… Now this looks more
like the performance gains promised by GPU computation.
