* Calculate the snake distance between two sets of coordinates (points).
*
* Snake distance (rectilinear distance, Manhattan distance) is the sum of the horizontal and vertical distances.
* It's the effective distance when movement is allowed only horizontally or vertically (but not both).
*
* @function Phaser.Math.Distance.Snake

* @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.
