HID: uclogic: Add support for UC-Logic TWHL850



Add support for UC-Logic Wireless Tablet TWHL850.
It is known to be sold as Genius MousePen M508W.

This tablet has a bug in the default (compatibility) mode which is used in this
driver: frame button assignments are mixed up. This is to be fixed with a driver
supporting the vendor-specific protocol.
