 * @param config General configuration for Subscription API subscriptions.
 * @param params Parameters specific to the API subscription.
 * @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.
 *
 * @throws {ValidationError} When the request parameters fail validation (before sending).
 * @throws {TransportError} When the transport layer throws an error.
 *
 * @example
 * ```ts
 * import { WebSocketTransport } from "@nktkas/hyperliquid";
 * import { userFills } from "@nktkas/hyperliquid/api/subscription";
 *
 * const transport = new WebSocketTransport();
 *
 * const sub = await userFills(

 *   (data) => console.log(data),
 * );
