ax206-usb-display-macos: driving the QDtech display over USB

ax206-usb-display-macos implements macOS control of a QDtech AX206-derived USB display. Its Python driver sends RGB565 frames through USB Mass-Storage Bulk-Only framing and the device's BLIT command; an image viewer and live system dashboard use that driver.
