Add GBDeviceCommandSendBytes for generic pre encoded commands that are meant to be send to a device directly

Browse Source 
This is useful for Debugging. We can now send answers to data from the Device directly
int he procol implementation without messing with code in the GBDEviceIoThread's implementation.

This commit also adds test code for interaction with WeatherNeat (so far nothing works though)
