TODO:
- 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
