Respond immediately when we get a STOP or repeated START while still selected. Otherwise, a START condition immediately preceded by a STOP could be missed. This probably will result in more clock stretching, but the ATmega firmware doesn't seem to handle retries, so it probably implicitly depends on the keyscanner doing clock stretching anyway. Anyway, the ATmega firmware seems to only issue STOPs when reading, so it's probably not too important in practice. (I only noticed when trying to do back-to-back LED commands that ended in STOPs.)

Prompt the user to press the bootloader trigger keys, both in the serial monitor and by lighting up the right LEDs (assuming there's already firmware that understands that.) Signed-off-by: Taylor Yu <[email protected]>
