deserializeJson(JsonVariant, ...)

It would be nice if the functions / methods serialzeJson() and deserializeJson() would be extended, so that it is possible to use them directly on nested Objects (and not only on the Json document). What I mean is extra function overloadings like this: size_t serializeJson(const JsonObject& object, char output[size]); deserializeJson(JsonObject& object, char* input);

For my MQTT project it would be very handy, because I have to serialise a portion of a json object.
