       This module provides a BSON type wrapper for the special BSON "MaxKey" type.  The object returned is a
       singleton.

TO_JSON
       If the "BSON_EXTJSON" option is true, returns a hashref compatible with MongoDB's extended JSON
       <https://github.com/mongodb/specifications/blob/master/source/extended-json.rst> format, which represents
       it as a document as follows:

           {"$maxKey" : 1}

       If the "BSON_EXTJSON" option is false, an error is thrown, as this value can't otherwise be represented
       in JSON.
