/**
 * A middleware function to estimate the gas usage of a user operation when using a Modular Account V2 WebAuthn account. Has an optional custom gas estimator.
 * This function is only compatible with accounts using EntryPoint v0.7.0, and the account must have an implementation address defined in `getImplementationAddress()`.
 *
 * @example
 * ```ts twoslash
 * import {
 *   webauthnGasEstimator,
 *   createSmartAccountClient,
 *   type SmartAccountClient,
 * } from "@aa-sdk/core";
 * import {
 *   createModularAccountV2,
 *   type CreateModularAccountV2ClientParams,
 * } from "@account-kit/smart-contracts";
 *
 * const credential = {
 *   id: "credential-id",
 *   publicKey: "0x...",
 * }
 *
 * async function createWebauthnAccountClient(
 *   config: CreateModularAccountV2ClientParams
 * ): Promise<SmartAccountClient> {
 *   const webauthnAccount = await createModularAccountV2({ ...config, mode: "webauthn", credential });
 *
 *   return createSmartAccountClient({
 *     account: webAuthnAccount,
 *     gasEstimator: webauthnGasEstimator(config.gasEstimator),
 *     ...config,
 *   });
 * }
 * ```
 *
 * @param {ClientMiddlewareFn} [gasEstimator] Optional custom gas estimator function
 * @returns {ClientMiddlewareFn} A function that takes user operation struct and parameters, estimates gas usage, and returns the user operation with gas limits.
