Problem 875. Return a list sorted by number of consecutive occurrences

Inspired by Problem 38 by Cody Team. Given a vector x, return a vector y of the values in x sorted by the number of CONSECUTIVE occurrences in x. Ties (and it is the difficulty) are sorted from lowest to highest. So if x = [1 2 2 2 3 3 7 7 93] then

 y = [2 3 7 1 93]

But if x = [1 1 2 2 2 3 3 7 7 1 93] then

 y = [2 1 3 7 1 93]
