Decide if this interval is certainly less than, possibly less than, or can't be less than `other` by returning `[true, true]`, `[false, true]` or `[false, false]` respectively. NOTE: This function only works with intervals of the same data type. Attempting to compare intervals of different data types will lead to an error.
