atusb-eui64: add utility to read/write and EUI64 from/to the device EEPROM

Together with the new fw version (starting with version 0.3) it is now possible
to set a permament EUI64 address into the devices EEPROM. The Linux driver will
get updated to choose this address, if available, instead of using a randomly
generated address.
