There already exist 2 rainbow LED effects, this adds a third, using
the LED-Stalker effect.
When you press a key, the LED on that key will cycle through all the
colors of the rainbow, independent of the colors of other keys.
While technically one can specify colors otherwise, for the sake of simplicity,
mention only `CRGB`, but do mention it explicitly, so the reader does not need
to look at the example to figure this out.
Fixes#9.
