I am no expert about PRNG, but according to some experts (the guys
who created xoroshiro, xorshift, etc.), "Our main 64-bit proposal for
an all-purpose, rock-solid generator is xoshiro256**". Moreover, it has a
quite simple implementation. What would be the "credentials" for
Tausworthe?

Do you have the code for this generator? Does it generate 64-bit numbers?
Is it easy to implement it even if the compiler does not support 64-bit
integers?
