/**
 * Calculate the Chebyshev distance between two sets of coordinates (points).
 *
 * Chebyshev distance (or chessboard distance) is the maximum of the horizontal and vertical distances.
 * It's the effective distance when movement can be horizontal, vertical, or diagonal.
 *
 * @function Phaser.Math.Distance.Chebyshev
 * @since 3.22.0
 *
 * @param {number} x1 - The x coordinate of the first point.
 * @param {number} y1 - The y coordinate of the first point.
 * @param {number} x2 - The x coordinate of the second point.
 * @param {number} y2 - The y coordinate of the second point.
 *
 * @return {number} The distance between each point.
