title: SVGO config file
body: <p>With svgo 1.3.2 I used to run this command :</p>
  <blockquote>
  <p>svgo --pretty --disable={removeUnusedNS,removeUselessDefs,removeUselessStrokeAndFill} file.svg -o file.min.svg</p>
  </blockquote>
  <p>I updated to svgo 2.3.0 and now I get :</p>
  <blockquote>
  <p>error: unknown option '--disable={removeUnusedNS,removeUselessDefs,removeUselessStrokeAndFill}'</p>
  </blockquote>
  <p>So I tried to create a svgo.config.js like this :</p>
  <pre><code>const { extendDefaultPlugins } = require('svgo');
  module.exports = {
    plugins: extendDefaultPlugins([
      {
        name: 'removeUnusedNS',
        active: false
      },
      {
        name: 'removeUselessDefs',
        active: false
      },
      {
        name: 'removeUselessStrokeAndFill',
        active: false
      }
    ])
  }
  </code></pre>
  <p>but I just get the error :</p>
  <blockquote>
