Suggestion: Noise functions for @std/random

[ArmaanAS]

Add the following noise functions to @std/random with function signatures like:

function perlin(x: number, y?: number, z?: number): number

function simplex(x: number, y?: number, z?: number, w?: number): number

I’ve been looking for a stable implementation of noise functions for some graphical use cases. It would be great if they supported seeding. There are more noise algorithms that are also useful for complex graphics but these two would be a good starting point.
