    image: Fix IMAGE_FEATURES determinism issue
    
    remain_features uses a dict which means the order is not deterministic. This
    can lead to the task hash changing depending on the state of the memory at
    parse time. This is particularly noticeable under python v3.
    
    Since the dict is helpful in constructing the data, pass the data through
    sort() so the order is always deterministic.
