HyperX QuadCast 2 S: reconstructing RGB control on macOS

HyperX QuadCast 2 S RGB control implements a macOS client for the microphone's USB HID lighting exchange. The source documents seven-packet color updates, acknowledgments, upper and lower LED zones, and IOKit collection selection and response draining. The app controls solid colors and brightness through a menu bar interface.
