Returns a range which contains all except the first/last count elements of range. These procedures run in O(1) time. The average accessing time of the resulting ranges is asymptotically bounded by the average accessing time respectively of range.

Examples:

(range->list (range-drop (numeric-range 0 10) 5))
  ⇒ (5 6 7 8 9)

(range->list (range-drop-right (numeric-range 0 10) 5))
  ⇒ (0 1 2 3 4)
