calibr_box.py is board specific (the type of box differ depending on the board).
Therefore it is removed from the common pts. If a mean to differentiate between
the box if implemented, it might come back to common pts.
cp210x driver is removed, because it is now stored in the usb-relay-box1 project's repo.
cp210x_eeprom.py is removed, because it is specific to the board (e.g. not the same for fmc-adc)
