When multiple components are using react-use-measure and a scroll event occurs, multiple react updates are executed serially.

I've got 9 components on screen which use react-use-measure, so a scroll event takes about ~2*9 =18ms to finish rendering. Shown below is 3 of the updates.

I use rafz for similar problems already (thank you by the way!), so this seemed like an elegant solution. It reduces the render time for my 9 components to ~9ms

I don't think this substantially changes the API for those not using rafz so I would hope it's not a breaking change? For those using it, they can opt in to batch their renders.

Thanks!
