Split icons into different packages

[sushantdhiman]

Is your feature request related to a problem? Please describe.
For server based application, it is required to keep node_modules folder even after bundling frontend app. This library bundles all icons together which increases overall image size.

Describe the solution you'd like
Even though this library provides @react-icons/all-files, I would like to see separate packages for each icon library, something like @react-icons/fa etc

Describe alternatives you've considered

• Considering this library https://github.com/styled-icons/styled-icons
• Manually (and dangerously) removing unused icons from node_modules
