 TODO:
    - Remove 128 bytes limit
    - Merge Uwe's eeprom tool. Current features:
        - Init eeprom defaults based upon eeprom type
        - Read -> Already there
        - Write -> Already there
        - Erase -> Already there
        - Decode on stdout
        - Ability to find device by PID/VID, product name or serial

 TODO nice-to-have:
    - Out-of-the-box compatibility with FTDI's eeprom tool configuration files
