fix(DASH): Correct SegmentTemplate range stop value

Browse Source 
Since range(start, stop) is start-inclusive but stop-exclusive, and DASH startNumber of SegmentTemplate typically will be 1 or not specified (defaulting to 1) it effectively worked by coincidence.

However, if startNumber was anything other than 1 than we will have a problem.
