Complete rewrite of [1]. Instead of a USB driver it`s now a HID driver
and will work without being part of the early boot environment.
The driver is no longer heavily tied to the Apple Studio Display, but
should work with all HID devices, that expose a report containing fields
with the Monitor - Brightness HID usage value.
