title: Laravel Mix generate fonts into another directory
body: <p>I'm using <code>laravel-mix</code> which is built on the top of the <code>webpack</code>. I'm facing a problem with fonts directory. For Example, <code>font-awesome</code> package has a scss file and a font directory where all fonts are placed. </p>
  
  <pre><code>font-awesome:.
  ├───scss
  │       fontawesome.scss
  └───webfonts
          fa-regular-400.eot
          fa-regular-400.svg
          fa-regular-400.ttf
          fa-regular-400.woff
          fa-regular-400.woff2
  </code></pre>
  
  <p>So i place this package in my <code>resources/assets/sass</code> directory.</p>
  
  <pre><code>resources:.
  └───asset
      └───sass
          │   main.scss
          │
          └───font-awesome (directory)
  </code></pre>
  
  <p><code>main.scss</code> contains code:</p>
  
  <pre><code>@import 'font-awesome/scss/fontawesome';
  </code></pre>
  
  <p><code>webpack.mix.js</code> contains:</p>
  
  <pre><code>mix.sass('resources/assets/sass/main.scss', 'public/css/frontend.css');
  </code></pre>
  
  <p>All assets are compiled successfully. Now <code>public</code> directory has a <code>css</code> and <code>font</code> directory, which has all fonts like this.</p>
  
  <pre><code>public:.
  │   index.php
  │
  ├───css
  │       frontend.css
  │
  ├───fonts
  │       fa-regular-400.eot
  │       fa-regular-400.svg
  │       fa-regular-400.ttf
  │       fa-regular-400.woff
  │       fa-regular-400.woff2
  </code></pre>
  
  <p>But What I want is, I don't want to compile all fonts into <code>public/fonts</code> directory i want to compile as following structure <code>public/fonts/vendor/font-awesome</code> </p>
  
  <pre><code>public:.
  ├───css
  │       frontend.css
  │
  └───fonts
      └───vendor
          └───font-awesome
                  fa-regular-400.eot
                  fa-regular-400.svg
                  fa-regular-400.ttf
                  fa-regular-400.woff
                  fa-regular-400.woff2
  </code></pre>
  
  <p>What changes that i need to change in <code>webpack.mix.js</code> file.</p>
