Added support for the Boox Palma 2 Pro.
Standard Qualcomm EPD works according to tests, but none of the existing light providers managed to effect the backlight.
Did a bit of digging and turns out Boox just changed the sysclass endpoints for backlight brightness (
onyx_bl_br) and colour temperature (onyx_bl_ct). Both work as standard backlight endpoints. On my unit, brightness max was 255 while temperature max was 32 - can't say this will apply to all devices (I suspect the Palma 2 uses the same endpoints albeit that model works with Onyx ADB and SDK implementations), so added dynamic reading of max values too.This change is
