change memory to calldata to save gas

[molly-ting]

Changing the data location of function parameters from memory to calldata can save much gas. In the following example, test4 saves about 955 units of gas.

    function test3(uint256[] memory amounts) public {
        uint256 amount = amounts[0];
    }

    function test4(uint256[] calldata amounts) public {
        uint256 amount = amounts[0];
    }

could someone take a look? I think this could save some gas.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
