Leaving the SVG as SVG instead of converting to string

[privatenumber]

Seems like this plugin is currently doing two things:

1. Optimizing the SVG with SVGO
2. Converting it to a JS module and exporting the SVG as a string

The second step makes the plugin un-interoperable with other Rollup plugins that take SVGs as an input.

For example, rollup-plugin-htmlvue takes in SVGs, converts them into a Vue SFC, and lets the Vue plugin then compile it to a JS.

Wondering if this plugin can become more modular by letting the SVG remain a SVG file, and recommending that users that want to import the SVG as a string chain their plugins with something like rollup-plugin-string:

import { rollup } from 'rollup';
import { string } from 'rollup-plugin-string';
import svgo from 'rollup-plugin-svgo'

rollup({
  entry: 'image.svg',
  plugins: [
	// optimize SVG
    svgo(),

	// transform SVG to JS string
    string({
      include: '**/*.svg',
    }),
  ]
});

Although my use-case is with Vue.js, I can imagine this being useful for optimizing SVGs that compile to React or Svetle components too.

That's a good idea. If it's still relevant a PR for doing this through an option would be great.
