Add custom Social Media Icons

# How to add custom social media icons to the font

## Description
I have a few links and icons to tools that are important to the company and would like to add them to the footer
social-media-section.
Per constants you can simply insert a link and label. Where I am stuck is how to elegantly add the icons to the webfont.
Or maybe create an own webfont.
Thanks for the help!

The issue does not identify a file, test, or entry point for the footer icons or webfont. Begin by locating the social-media-section and the existing icon-font setup in the Bootstrap Package; the work would be done when a documented, maintainable way to add the requested custom icons is established.
