LED Status Indicator

The ftSwarm controllers indicate their operating status via RGB LEDs:

LED	Description
	Controller is powered off. Check the power supply.
	Controller is booting.
	wifi is starting.
	Ready for operation.
	The controller has encountered an error. Wifi connection issues are often the cause.
	Waiting for an I/O that is still offline. Check the log.
	Identify. To locate a controller within a larger swarm, it can be marked light blue via the CLI.
	A fatal error has occurred. All motors have been shut down and program execution has been terminated. Check the logs.
	If, when resetting a controller, the S1 button or a pushbutton on A6 is pressed and released while the LEDs are lit purple, the controller will reset to factory settings.

The ftSwarmControl has no LEDs and instead displays its status via the OLED display.
