 * GenericFeeEstimator is a class that implements the IFeeEstimator interface. You can implement three optional methods that will be called during the estimation process:
 * - preEstimateUserOperationGas: Setup the userOperation before calling the eth_estimateUserOperation gas method.
 * - postEstimateUserOperationGas: Adjust the userOperation values returned after calling the eth_estimateUserOperation method.
