Given a 2D array of integer (length > 0), return true if any two consecutive values are the same. A consecutive value is either two values from the same row in neighboring columns, or the last column in one row compared to the first column in the next row.

Example:

consecutive([[1, 2, 3], [3, 4, 5], [6, 7, 8]]) --> true
consecutive([[1, 1, 2], [3, 4, 5], [6, 7, 8]]) --> true
consecutive([[0, 1, 2], [3, 4, 5], [6, 7, 8]]) --> false
