/**
 * This proc generates a cellular automata noise grid which can be used in procedural generation methods.
 *
 * Returns a single string that goes row by row, with values of 1 representing an alive cell, and a value of 0 representing a dead cell.
 *
 * Arguments:
 * * percentage: The chance of a turf starting closed
 * * smoothing_iterations: The amount of iterations the cellular automata simulates before returning the results
 * * birth_limit: If the number of neighboring cells is higher than this amount, a cell is born
 * * death_limit: If the number of neighboring cells is lower than this amount, a cell dies
 * * width: The width of the grid.
 * * height: The height of the grid.
