Create a function that takes an array of integers (positive / negative) and return the sum of the numbers that repeat consecutively (return your result as an array).
sumConsecutives([0, 7, 7, 7, 5, 4, 9, 9, 0]) ➞ [0, 21, 5, 4, 18, 0]
sumConsecutives([4, 4, 5, 6, 8, 8, 8]) ➞ [8, 5, 6, 24]
sumConsecutives([-5, -5, 7, 7, 12, 0]) ➞ [-10, 14, 12, 0]
