Function scaleArrayByFactor

This function will scale any given 2-dimensional array this will be scaled, this will be scaled by a given factor. Inspired by Stackoverflow Answer

const arr: number[][] = [[1,4]]
const factor: number =  2;

// will return [[1,1,4,4]]
const scaledArr: number[][] = scaleArrayByFactor(arr, factor);

if you want to scale multidimensional array, use a recursion as a wrapper.

@param {any[][]} arr Any 2-dimensional array to be scaled @param {number[][]} factor the factor to scale the given array.

@return {string[][]} returns the scaled array by factor.
