/**
 * @module
 *
 * This module provides functionality to interact with and retrieve tile data from `.versatiles` container files,
 * typically used for storing geospatial tile data in a compressed, optimized format. The module supports
 * multiple file and compression formats.
 *
 * Dependencies:
 * - `HttpReader` and `FileReader`: Adapters for reading data from HTTP/HTTPS URLs or local files, respectively.
 * - `decompress`: Utility for decompressing tile data in supported formats.
 * - Type definitions (`Block`, `Compression`, `Format`, `Header`, `OpenOptions`, `Reader`, and `TileIndex`)
 *   from the module's `interfaces.js` file to ensure type safety and consistency.
 *
 * Exported Constants:
 * - `FORMATS`: Supported formats organized by version for different tile data, including image formats (e.g., PNG, JPG)
 *   and vector formats (e.g., PBF).
 * - `COMPRESSIONS`: Available compression types, including 'raw' (no compression), 'gzip', and 'br' (Brotli).
 * - `MIMETYPES`: Maps supported tile formats to their respective MIME types for handling and delivery.
 *
 * Exported Types:
 * - The module re-exports `Compression`, `Format`, `Header`, `OpenOptions`, and `Reader` types for use in other modules.
 *
 * Primary Class:
 * - `Container`: A main wrapper class that provides methods to access tile data, metadata, and configuration settings
 *   for `.versatiles` containers. Methods include `getHeader`, `getMetadata`, `getTile`, and `getTileUncompressed`,
 *   which enable detailed control and retrieval of tile information, metadata, and decompressed content.
 *
 * @example
 * ```ts
 * import { Container } from '@versatiles/container';
 * const container = new Container('path/to/versatiles-file');
 * const tile = await container.getTile(12, 2200, 1343);
 * const metadata = await container.getMetadata();
 * ```
