docs: Returns a string of random, space separated, ASCII words.
  
      These words are of the given language and from the given wordlist.
      There will be `nwords` words in the string.
  
      `bits_per_word` determines the amount of entropy provided by each word;
      when it's higher, this function will choose from a larger list of
      words, some of which are more rare.
