Handle or report all error codes returned from sensors

[ThirteenFish]

We currently ignore this. I don't imagine that there are many or any errors that we can handle dynamically, so in most cases it should send the information over ethernet to the FC for logging.

How it gets sent is a matter to consider, this is a first attempt at what we came up with: For errors attached to specific samples:

• Send an extended data packet on the data port that has the errors amended For more general sensor errors:
• Send them on a special sensor error port

The important thing is to not mix general errors on the sample specific data port.
