Expose the extra pads on the nice!nano for the rotary encoder and allow for the main user button to be connected to the rotary encoder button as well #62

Description

@mofosyne

I noticed that adding a rotary encoder would not work for faketech v5 as it would take up the gpios that's meant for high current drive outputs for buzzer and vibration motor.

If you make an updated revision, please expose extra pads (you have 4 gpio in total that is currently inaccessible from the back of faketecV5).

I did notice that https://github.com/jtljac/fakeTec_pcb made a fork which included such changes to expose those three pins for the encoder (but still leaves pin 12 unconnected... so that's a waste of a gpio once an OLED screen is attached above making it inaccessible).

Also I would like it if you could also add a solder bridge switch, so that the encoder button can be connected to the user button.
This is because when I shown it to another person, he found it hard to use the rotary button 'select' to select letters and wished that he could do so with the user button instead. However meshtastic firmware currently doesn't seem to have a way to disable the user button feature so it can behave as an extra 'rotary' button select instead.
