Use modern alternative for random functions

[browner12]

My understanding is random_int is only required for cryptographically secure random number generation.

While they both do work for random number generations, random_int can be less performant than mt _rand/rand. Even in my very basic 3v4l script below, mt_rand is about twice as fast as random_int.
