CSS sprite possible?

[tbredin]

Love these flags — and it would be awesome if there was a way to import these as a CSS sprite.

Detailed Description

In some circumstances you might not be able to use React, Vue, or Svelte to display flags. It would be great if there was an image sprite option with some css for positioning the sprite.

Is your feature request related to a problem? Please describe.

For example my team is using a plain js library that generates markup for an international phone number input which displays flags as you type. By far the simplest way to replace the flags used would be to provide some CSS to override the existing classes.
