LayerState_LED is similar to LayerState introduced in keybrd_3a_multi-layerHold.ino, but with LEDs.
The LayerState_LED turns on the LED of the active layer.
The prtsLayerLEDs[] array contains one LED per layer.
The active layerId is used as an index to dereference the prtsLayerLEDs[] array.

When a Code_LEDLock object is pressed, it sends its scancode and updates the its LED.
Scancodes can be one of: KEY_CAPS_LOCK, KEY_SCROLL_LOCK, or KEY_NUM_LOCK.
For example, when o_capsLock is pressed, it sends KEY_CAPS_LOCK scancode and updates LED_capsLck.
