Use a newest inventory library instead of Ampmenus

[luiz-otavio]

Recently I was working with WRLD-Payments-API, but for some reason I couldn't attach it to my plugin due to some dependency issues like ampmenus. I tried getting the ampmenus repository and then load it, however, it doesn't exist anymore.

After looking in pom.xml of this project, I found that there is repository which has the ampmenus, but it gave me a lot of work for just one library...

There are another libraries like SmartInvs, inventory-framework and whatever which could help with the same idea.

Thanks, we’ll replace it with inventory-framework.
