Is your feature request related to a problem?

When using flexbox to arrange, say, images, it can be useful to take advantage of CSS' ability to easily put gaps between the items.

Describe the solution you'd like

Add spacing variants for the CSS gap property based on the space helper values.

(Here are the caniuse.com stats for gap support in flexbox.)

Describe alternatives you've considered

It's possible to generate the variants myself, in siimple.config.js. But maybe others would find this a useful addition too?
