title: Add support for next-css and next-less simultaneously in next.config.js
body: <p>I am using nextJs and need to add support for both less and css. I want to have next-css and next-less both for a project. But It accept one at a time. Here is what I am using</p>
  
  <pre><code>const withCSS = require('@zeit/next-css')
  module.exports = withCSS({
    /* config options here */
  })
  
  const withLess = require('@zeit/next-less')
  module.exports = withLess({
      cssModules: false,
      lessLoaderOptions: {
          javascriptEnabled: true
      }
  })
  </code></pre>
  
  <p>Am I including both loaders correctly? And I need javascriptEnabled: true too. How can we acchieve this configuration. </p>
  
  <p>I really appreciate if you can give any hint or two.</p>
