The Arctic RGB controller support 4 RGB channel and can be controlled
over a CH341 USB-to-serial chip. The controller support two commands,
one for identifying the controller on a serial port and one for setting
the RGB values for each RGB channel. Since the controllers disables the
RGB channels after ~1s, a keepalive thread is used.
