Fixes https://github.com/googlefonts/fontbakery/issues/551 the `codes` variable needs to be a sorted list of cmap keys, else the following line ```python codes = range(codes[0], codes[-1] + 1) ``` cannot work properly, since dict keys are unsorted. Up until 13a08d0c3a59402459875155b7dbd194787fb229, there was a line with ```python codes.sort() ``` which was deleted for some reason.
