Fetch the raw JSON game state data from EchoVR's ``/session`` API

        This method could be useful if you want to retrieve some API data not
        directly exposed by this Python wrapper. Otherwise, you should probably
        use :meth:`fetch_state` instead.

        :returns:
            An object (probably a :class:`dict`) representing the raw JSON
            response returned by the EchoVR client.

        :raises requests.exceptions.ConnectionError:
            This exception will be thrown if the API is unavaible. This might
            indicate that the user is not currently in a match, or that they
            didn't launch Echo VR with the `-http` option.

        :raises json.decoder.JSONDecodeError:
            This exception will be thrown if the data returned by the API is not
            valid JSON. Likely indicates a bug in Echo VR or in this library.
