📄 Description

This adds the possibility for a pushbutton on the tag. A button press causes an interrupt to wake from sleep, and triggers an update immediately.
Use #define HAS_BUTTON to turn this on/off.
To connect a button to the tag, use TEST-pin and GND, and place a capacitor of about 100nF in parallel to the switch. Due to the (internal) input pin pull_up resistor, I'm not sure how much extra current this will draw. I'm currently not able to measure microamperes, so this is to be determined.
