/**
 * @assertion List<int> dictionary
 * Initial compression dictionary.
 * It should consist of strings (byte sequences) that are likely to be
 * encountered later in the data to be compressed, with the most commonly used
 * strings preferably put towards the end of the dictionary. Using a dictionary
 * is most useful when the data to be compressed is short and can be predicted
 * with good accuracy; the data can then be compressed better than with the
 * default empty dictionary.
 * @description Checks that [dictionary] is set correctly with values null or
 * List<int>.
