docs: Decode the number to a string using the given statistics.
  
      This is a wrapper for :py:meth:`Arithmetic.decode`.
  
      Parameters
      ----------
      longval : int
          The first part of an encoded tuple from ac_encode
      nbits : int
          The second part of an encoded tuple from ac_encode
      probs : dict
          A probability statistics dictionary generated by
          :py:meth:`Arithmetic.train`
  
      Returns
      -------
      str
          The arithmetically decoded text
  
      Example
      -------
      >>> pr = ac_train('the quick brown fox jumped over the lazy dog')
      >>> ac_decode(16720586181, 34, pr)
