This problem was inspired by a tweet I saw from @MATLAB regarding The Warholer.
Given an MxNx3 array (A) representing an image and a threshold for each channel (r/g/b), generate a new array (B) whose elements are 255 if greater than the threshold for that channel or 0 otherwise. This means the new "image" will only have 8 colors.
You may assume that the inputs are on the interval [0,255].
