Duet 2 WiFi and Duet 2 Ethernet

The miscellaneous pin numbers 60-63 correspond to the CS5-CS8 pins on the expansion connector. These were originally allocated for use as the E2-E6 endstop pins and are labelled as such on the expansion connector, but they are now used to address thermocouple and PT100 daughter boards on a Duex 2 or Duex 5 instead. Because most users don't need more than the four thermocouple and PT100 channels supported on the Duet 2, we make CS5-8 available as general purpose I/O if you do not have any daughter boards fitted to the Duex 2 or 5.
