Types for ymaps3 maps library

import type { Projection, LngLat, WorldCoordinates } from "../../common/types";
/**
 * Creates a projection of a rectangular coordinate area into world coordinates.
 * The area size in pixels is always 2*2.
 *
 * @name Cartesian
 * @class Cartesian projection of a rectangular area.
 * @augments Projection
 * @param {[[Number, Number], [Number, Number]]} bounds An array of two points -
 * coordinates of the lower left and upper right corners of the rectangular coordinate area.
 * @param {Boolean[]} [cycled=[false, false]] An array of signs of map looping by x and y.
 * @example
 * ```js
 * ymaps3.ready(async () => {
 *     const {YMaps} = ymaps3;
 *     // Calculate the size of all tiles at the maximum zoom.
 *     const worldSize = Math.pow(2, MAX_ZOOM) * 256;
 *     const PIC_WIDTH = 2526;
 *     const PIC_HEIGHT = 1642;
 *
 *     const {Cartesian} = await ymaps3.import('@yandex/ymaps3-cartesian-projection@0.0.1');
 *     // We set as a projection Cartesian. With this calculation, the center of the image will lie in the coordinates [0, 0].
 *     const projection = new Cartesian([
 *         [-PIC_WIDTH / 2, PIC_HEIGHT / 2 - worldSize],
 *         [worldSize - PIC_WIDTH / 2, PIC_HEIGHT / 2],
 *     ]);
 *
 *     const map = new YMaps({
 *         //...,
 *         projection: projection
 *     });
 * });
