prefix - For a given start prefix (inclusive), returns the correct end prefix (non-inclusive).
This assumes the key bytes are ordered in lexicographical order.
Since key length is not limited, for some case we return
Nonebecause there is no bounded limit (every keys in the serie[],[255],[255, 255]…).
