/**
 * `getRawPackument` returns the packument (package document) containing
 * all the metadata about a package present on the registry.
 *
 * Note: the packument is returned as retrieved from the registry.
 *
 * @param name - package name
 * @param registry - URL of the registry (default: npm registry)
 * @param mirrors - URLs of the registry mirrors (default: npm registry mirrors)
 * @param cached - accept cached responses (default: `true`)
 *
 * @example
 * Get the packument for package `query-registry` from the npm registry:
 *
 * ```typescript
 * import { getRawPackument } from 'query-registry';
 *
 * (async () => {
 *     const packument = await getRawPackument({ name: 'query-registry' });
 *
 *     // Output: 'query-registry'
 *     console.log(packument.name);
 * })();
 * ```
