The I2C code is based on the code from 'handwired/dactyl',
but reduced to ROW2COL and EXPANDER_COL_REGISTER=GPIOA define choices.
Adjustments were made for the two I2C addresses, one per side.


## Bootloader

Enter the bootloader in 2 ways:

* **Physical reset button**: Briefly press the button on the Teensy by inserting a small pin in the small hole in the switch plate
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
