Check that a versioned dimension is temporally coherent, per key
Check that a versioned dimension is temporally coherent, per key. Reports intervals that overlap, so a point-in-time lookup returns two rows; gaps, so it returns none; more than one live version; an interval ending before it starts; and a current flag that disagrees with its own interval. Intervals are treated as half-open, so a row ending exactly where the next begins is contiguous rather than overlapping.
