Feature Request: Icon selection for CDN
This is only applicable for those who use the CDN provided by remixicon.com

As most developers would know not all icons are necessary for their application, and loading unnecessary content slows down the page load times so it would be really nice if the developer could select what icons they would like to use and generate a unique token based on their selection. As the scope of the projects increases the load does so too, say for instance when in the future there are 10,000+ icons and the application only really needs 20 or 30. 

Here's an example:

Lets just say for example I only want the icons `folder` and `tv` and I would be prompted with a CDN url of the following: https://cdn.remixicon.com/releases/v2.1.0/remixicon.css?token=RANDOMTOKEN

And in turn it would provide me with those relevant icons and the css to go with it. Cutting down on the page load time and I'm sure bandwidth for Remix Icon itself. Win Win.
