AddToAny With A Strict CSP

Use a nonce

1. Generate a nonce per request, for example:
   MTIwMDk3MDM0Myw3OTA2ODIxMzc=
2. Include the nonce in your strict CSP: Content-Security-Policy: script-src 'nonce-MTIwMDk3MDM0Myw3OTA2ODIxMzc='
3. Add the nonce attribute to your AddToAny <script> tag like so:
   <script async nonce="MTIwMDk3MDM0Myw3OTA2ODIxMzc=" src="https://static.addtoany.com/menu/page.js"></script>
