Swapped byte detection in Multi Channel Encapsulation.
This code detects swapped bytes in Multi Channel Encapsulation messages
sent to the controller. The controller has no endpoints and therefore
should always be addressed as 1, while originating can be between 1 and
- When destination != 1 for the controller, the packet is invalid.
The greenwave nodes make this mistake in their firmware.
Fixes #738.
