wl_rand --> bits_R is not used

[Saadmaghani]

Hey, thanks for the great repo!

I noticed that the bits for random are not used in QG. They dont seem to be used at all. The original paper says they use this to "16-bit random number generator to constrain high bitwidth gs to kG-bit integers stochastically"

Not sure how/where they implement this in their repo though. Would be great if its looked into it in pytorch!
