This adds a uniquifySorted function to remove duplicates from sorted arrays. The function has O(n) time complexity and works with uint256, address, and bytes32 array types. This is particularly useful when mappings cannot be utilized, and provides an easy way to combine Array.sort() + Array.uniquifySorted().
