Is your feature request related to a problem? Please describe.
No, but would be nice to have a single sanitizing library/package

Describe the solution you'd like
SVG files, unlike other image formats are based on XML so they can store malicious tags eg:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" baseProfile="full" >
   <polygon id="triangle" points="0,0 0,50 50,0" fill="#009900" stroke="#004400"/>
   <script type="text/javascript">
      alert(document.domain);
   </script>
</svg>

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 500 500">
    <script>//<![CDATA[
        alert(document.domain)
    //]]>
    </script>
</svg>
