Version 1.8.0

Add new animateProperties(duration:animations:completion:) method.

This allows you to animate any of the animatable properties of the UICircularProgressRing, which currently are: innerRingColor, innerRingWidth, outerRingColor, outerRingWidth, innerRingSpacing, fontColor.

Example usage:

self.ring.animateProperties(duration: 1.5) {
	// Animate things here
	self.ring.innerRingColor = .purple
	self.ring.outerRingColor = .blue
}
