Add composer.libraries.json to the project (both branches)

I added the library in the main composer.json file and I was able to download it with no issues:

Using version ^4.8 for infusion/infusion

I'll merge it to the 3.0.x branch and open a new MR for the 2.0.x branch.

This MR worked as well:

daniel@drupal:/var/www/html$ 

I'll merge this to the 2.0.x branch and update the <code>README.md

files on both branches to indicate the user that they can download the library from this alternative way.

For now I'll mark this as "Fixed" unless someone has any issues, I can re-open it of course.
