Describe the bug When the Social Media Share Buttons & Social Sharing Icons is used with either Delay JS or Defer JS, and the jQuery library is excluded, the following console error shows up:

Uncaught Error: Shuffle.js requires Modernizr.
http://vestride.github.io/Shuffle/#dependencies
    at jquery.shuffle.min.js?ver=6.0.1:1:177
    at jquery.shuffle.min.js?ver=6.0.1:1:85
    at jquery.shuffle.min.js?ver=6.0.1:1:119

In addition to the console error, the buttons don't show up.

Excluding the following from Delay JS and Defer JS (when jQuery is already excluded) fixes the issue:

/ultimate-social-media-icons/js/shuffle/modernizr.custom.min.js

Not pushing a PR as this will require a compatibility file to manage both exclusions.

To Reproduce Steps to reproduce the behavior:

1. Enable the Social Media Share Buttons plugins
2. Add the bottoms to the page from the settings
3. Exclude jQuery from either Defer or Delay JS
4. See error

Expected behavior There shouldn't be any errors when the Social Media Share Buttons is used with Delay and Defer JS, even if jQuery is already excluded.
