Fix code affected by a breaking change in msgpack 1.0

The msgpack readme explains: "Default value of strict_map_key is changed to
True to avoid hashdos. You need to pass strict_map_key=False if you have data
which contain map keys which type is not bytes or str."

chinese.py loads SIMPLIFIED_MAP from disk.  Since it is a str.translate
dictionary, its keys are numbers.  And since it's a dictionary we created
ourselves, there's no hashdos concern, so we can load it with
strict_map_key=False.
