 * @param listener A callback function to be called when the event is received.
 * @param options Options to control the subscription lifecycle.
 * @return A request-promise that resolves with a {@link ISubscription} object to manage the subscription lifecycle.

 * ```ts

 * import { allMids } from "@nktkas/hyperliquid/api/subscription";
 *
 * const transport = new WebSocketTransport();
