At present, Adafruit's rotary encoders all move 1 quadrature cycle per detent, so we originally hard-coded division-by-4. However, other encoders exist, including ones without detents, ones with 2 detents per cycle, and others with 4 detents per cycle. The new `divisor` property and constructor argument allows selecting a divisor of 1, 2, or 4; with the default of 4 giving backward compatibility. The property is not supported (yet?) on espressif MCUs; it throws an error if a value other than 4 is set.
