Is your feature request related to a problem? Please describe.

Spritemaps are a more optimal solution to loading SVGs. We should use an svg spritemap generator to create class names with the necessary SVG reference.

Describe alternatives you've considered

Additional context

We've tried SVG in TS code, creates bloat.
We've tried SVG loading in CSS, it loads when the user is looking at it resulting in unwanted animation
