Uses wrong interface for UniswapV2Pair.sol in the Tarot Oracle. The state variable reserve0CumulativeLast inside IUniswapV2Pair.reserve0CumulativeLast does not exist, and will revert when called in the Tarot Oracle, during Mix Oracle use.
Note: Tarot Oracle hasn't ran in 1 year
Official UniswapV2Pair.sol uses price0CumulativeLast instead of reserve0CumulativeLast.

Mix oracle broken as a result of tarot oracle breaking, which means this backup oracle fails which is bad.
