The images take some time before being displayed after a scroll event

The user experience using the component is currently not great. If I scroll a bit too fast (but an acceptable speed for a user), we'll see that the images are not loaded.

Hmm, I'm not sure what's happening here - although I can see white space if scrolling very fast it isn't this bad in my experience.

There's definitely a trade off to be made between performance and UX, but I think we could probably double the overscanRowCount from 10 to 20 or so to make this better…

@tommoor awesome project!
I believe this is happening because the use of cdn.jsdelivr.net and each emoji image requested separately.

As this project already React, could we use instead of the main emojione repo something like: https://github.com/pladaria/react-emojione
Which just renders the pre downloaded images.
