Add support for MSI GL66

Initial commit for MSI GL66

#2705

This adds support for the MSI GL66. The MSI Pulse GL66 has an internal keyboard with a USB RGB controller. The RGB controller is on a USB interface while keypress detection uses a separate non-usb interface. The code is based off the 162 byte MSI controller code. This laptop only has one zone. The controller has an off mode, a steady mode and modes that transition between up to 7 colors. While exploring the controller, I discovered a pulse and double pulse mode.

I verified the code to work on Linux Mint 21. It uses the HID-USB library so it should work cross-platform.
