Remove ref reads during render in CSS transition polyfill

Fix #207

This diff updates the `useStyleTransition` hook to utilize the hook equivalent of the"getDerivedStateFromProps" pattern — which ultimately means to "set state" in render instead of writting/reading refs during render.

The only annoying part of this change is needing to do a deep comparison of the style objects since their identies are almost guaranteed to change every render. I've mitigated the performance implications of this by only comparing the style properties which are designated by `transitionProperties`. This does create some limitations in terms of how close we can get to exactly the browser's behaviro wrt CSS transitions but in my testing that limitation was already present before my changes so at least it isn't a regression.

This strategy also inherently provided some improvements like avoiding unecessary `interpolate` calls and unnecessary animations being triggered.
