MeterbusFrameSerializer Serializing ControlFrames not complete

[RJvdBerg]

Hello.

In the lib, the serializer responsible for creating the ControlFrame data, it seems like the Control frame, Address, and ControlInformation is missing.

I added it to my code, should anyone not get a response from the meter, using this ControlFrame, be aware that this critical data pieces is missing.
