Make it work with struct array

[climber2002]

Original implementation doesn't work for following method with struct array as parameter

  struct PairOut {
    address pairAddress;
    uint256 amountOut;
  }

function action(
    uint256 amount,  
    PairOut[] calldata pairOuts
  )

The function signature is action(uint256,(address,uint256)[])

BTW thanks for providing such a useful tool!
