naw.RandomWordAug() doesn't have parameter aug_max

[RenShuhuai-Andy]

Hi~
init function of class naw.RandomWordAug doesn't have parameter aug_max:

class RandomWordAug(WordAugmenter):
    def __init__(self, action=Action.DELETE, name='RandomWord_Aug', aug_min=1, aug_p=0.3, stopwords=None,
                 target_words=None, tokenizer=None, reverse_tokenizer=None, stopwords_regex=None, verbose=0):
        super().__init__(
            action=action, name=name, aug_p=aug_p, aug_min=aug_min, stopwords=stopwords,
            tokenizer=tokenizer, reverse_tokenizer=reverse_tokenizer, device='cpu', verbose=verbose,
            stopwords_regex=stopwords_regex)

        self.target_words = ['_'] if target_words is None else target_words

I don't know if it was intentional or missed?
