Using MinMax aggregators to find the first start time and the last end time of an IItemCollection is incredibly inefficient, since we're iterating through every event in lanes already sorted by timestamp. If we instead use the fact that these lanes are sorted, we can skip performing very costly comparisons and instead just get the first or last events in each lane and find the event in that set that was earliest or last, respectively.
