 * @function create
 * @param {object} options Creation options:
 * @param {Client} [options.client] A {@link Client} instance.
 * @param {string} [options.authorization] A tokenizationKey or clientToken. Can be used in place of `options.client`.
 * @param {boolean} [options.useDeferredClient] Used in conjunction with `authorization`, allows the Apple Pay instance to be available right away by fetching the client configuration in the background. When this option is used, {@link ApplePay#createPaymentRequest} will return a promise that resolves with the configuration instead of returning synchronously.
 * @param {callback} [callback] The second argument, `data`, is the {@link ApplePay} instance. If no callback is provided, `create` returns a promise that resolves with the {@link ApplePay} instance.
 * @returns {(Promise|void)} Returns a promise if no callback is provided.
