Swap

Create swap EIP 5792 calldata

Create the EIP 5792 calldata for a swap transaction (including wrap/unwrap and bridging) against the Uniswap Protocols. If the quote parameter includes the fee parameters, then the calldata will include the fee disbursement. The gas estimates will be more precise when the response calldata would be valid if submitted on-chain.
