> Implement function {{zip_with_index(array[, indexFirst])}} that transforms the input array by encapsulating elements into pairs with indexes indicating the order.
> Examples:
> {{zip_with_index(array("d", "a", null, "b")) => [("d",0),("a",1),(null,2),("b",3)]}}
> {{zip_with_index(array("d", "a", null, "b"), true) => [(0,"d"),(1,"a"),(2,null),(3,"b")]}}
