ReadyNAS RN426: reconstructing front-panel control under TrueNAS

The ReadyNAS RN426 panel project reconstructs front-panel control from NETGEAR's stock firmware so the LCD and navigation buttons work under TrueNAS SCALE. Its Python driver bit-bangs the SSD1305-class display through Denverton GPIO registers and reads button state from an MSP430 over SMBus when its interrupt fires.
