Icons are in root folder on build

[SamGamegie44]

Hello,

First, thank you for this library, it's great 👍

My problem is: when I build my project (ng build), all svg are stored in root folder beside the built main files.

Could you put all those files in a directory? Maybe in the assets folder like this:

• dist
  • webapp
    • assets
      • fonts
      • images
      • material-icons
      • stylesheets
      • file-icon-vectors
        • all svg icons
        • ...
    • favicon.ico
    • index.html
    • main.js
    • main.js.map
    • main.js.map
      ...

Regards
