 * import { createSmartAccountClient } from "@aa-sdk/core";
 *
 * const alchemyTransport = alchemy({
 *  chain: sepolia,
 *  apiKey: "your-api-key"
 * });
 *
 * const client = createSmartAccountClient({
 *  feeEstimator: alchemyFeeEstimator(alchemyTransport),
 *  ...otherParams
 * });
 * ```
 *
 * @param {AlchemyTransport} transport An alchemy transport for making Alchemy specific RPC calls
 * @returns {ClientMiddlewareFn} A middleware function that takes a transaction structure and fee options, and returns the augmented structure with estimated fees
