docs: Check whether a short number is a possible number.
  
      If a country calling code is shared by multiple regions, this returns True
      if it's possible in any of them. This provides a more lenient check than
      is_valid_short_number.
  
      Arguments:
      numobj -- the short number to check
  
      Return whether the number is a possible short number.
