/// @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>. The default value is null.
