I originally benchmarked my implementation against a bunch of other ones in c
(because I was developing a c library
https://github.com/camel-cdr/cauldron/blob/main
I tried to implement a different implementation of the ziggurat method for
generating standard normal distributions that is about twice as fast and uses
2/3 of the memory than the old one.
I tested the implementation separately and am very confident it's correct, but
it does fail 28 test in cove
