Analog input

[RepRapLtd]

Hi!

This looks like a really useful project. Brilliant!

I have a feature request, if that's all right: add a single analogue input to the ESP-32 accessible from the outside. Ideally this would be a 3-way connector with GND, VDD3V3 and (say) a connection to GPIO34. This would allow measuring and monitoring of things like light levels and temperatures. The latter would be really useful if the device were to be used, for example, to control heating in buildings. It could not only turn the heaters on and off; it could also then transmit back the room temperature. This would allow central systems access to both monitoring and control.
