-This method is used for configuring and setting up properties of the partial `userOp` object. It converts an individual transaction or batch of transactions into a partial user operation populating fields such as initCode, sender, nonce, maxFeePerGas, maxPriorityFeePerGas, callGasLimit, verificationGasLimit and preVerificationGas (as this step also involves estimating gas for the userOp internally)
