Initial HyperX Eve 1800 SignalRGB plugin and protocol tools

Working 10-zone plugin using the 0x44 live colour reports on the 0xFF90
vendor interface (data then commit). Includes Python tools used to
identify the device, confirm the protocol and map zones. Output is
dimmer than onboard effects; investigation pending.
