Remarks
This is xoshiro256** 1.0, our all-purpose, rock-solid generator. It has
excellent(sub-ns) speed, a state space(256 bits) that is large enough
for any parallel application, and it passes all tests we are aware of.
For generating just floating-point numbers, xoshiro256+ is even faster.
The state must be seeded so that it is not everywhere zero.If you have
a 64-bit seed, we suggest to seed a splitmix64 generator and use its
output to fill s.
