AddToAny With A Strict CSP

Use a nonce

1. Generate a nonce per request, for example:
   MTk3MTIwODU4OCw2MzY5Mzk5NzI=
2. Include the nonce in your strict CSP: Content-Security-Policy: script-src 'nonce-MTk3MTIwODU4OCw2MzY5Mzk5NzI='
3. Add the nonce attribute to your AddToAny <script> tag like so:
   <script async nonce="MTk3MTIwODU4OCw2MzY5Mzk5NzI=" src="https://static.addtoany.com/menu/page.js"></script>
