UART Gnss: Added fletcher calculation:
Communication is verified using the Fletcher check. In the example code the commands were har coded including the check bytes. To make definition of new commands easier the check bytes are now calculated at runtime. This may be referted to hardcoded values once the implementation is getting a mature state.
