v3.0.0

• Move logic from a single huge class component into several smaller, more maintainable components and hooks
• Add "cell decorators" to provide an easy way to add common hover animations -- for example, wrapping renderItem in a <ScaleDecorator> component will automatically scale the active item (see above gif). Added scale, shadow, and opacity decorators, and developers may create their own custom decorators via useOnCellActiveAnimation hook.
• Remove onRef prop in favor of forwardRef
• Remove layoutInvalidationKey: we no longer need to force re-measurement, each cell now automatically re-measures on layout
