/**
 * Validation function to check if an item has a valid extent and is not set to the world extent
 *
 * The socring logic is as follows:
 * - If the item does not have an extent or the extent is not an array of two arrays, a message is added and the it receives no score.
 * - If the extent is not a valid extent object (not an array of two coordinate pairs, or coordinates are out of range), a message is added and receives no score.
 * - If the extent is valid, the rule receives a scoring factor for having a valid extent.
 * - If the extent is not set to the world extent, the rule receives an additional scoring factor for having an appropriate extent.
 *
 * @param item - item to validate
 * @returns validation info object
 *
 * @example
 * ```ts
 * import { validateItemExtent } from 'living-atlas-content-validator';
 *
 * const item = {
 *   extent: [[-10, -10], [10, 10]]
 * };
 *
 * const result = validateItemExtent(item);
 * console.log(result);
 * ```
