BUG: config class "__repr__": not JSON serializable

[HarryWangLaTrobe]

In the class Config:

def __repr__(self):
        return json.dumps(Config._cfg)

However, this conflicts with:

    @property
    def bool_names(self):
        if "bool_names" in Config._cfg:
            names = Config._cfg["bool_names"]
        else:
            names = (b"FALSE", b"TRUE")  ## <-- this causes error
        return names

The byte type is not JSON serializable.

Therefore, the error is triggered each time when repr is called, e.g. print

This bug causes the dysfunction of h5pyd.get_config, e.g.
h5pyd.get_config( config_file= "./data/hsds.server.hscfg" )

suggested solution: either remove the byte data field or use the Python built-in True/False data type
