ASUS XG34WCDG: mapping DDC/CI monitor controls

The ASUS XG34WCDG reference maps DDC/CI controls for display modes, colour, HDR, OLED care, proximity sensing and Aura effects. It correlates VCP values with on-screen changes and reports observed write and readback behavior on one unit, while separately describing the USB Aura interface from host records and published sources.
