What is the current behavior? (You can also link to an open issue here)
Currently, getting the following error while trying to lazily load NgxModule:

ERROR NullInjectorError: R3InjectorError(AppModule)[LayoutService -> LayoutService -> LayoutService]:
NullInjectorError: No provider for LayoutService!
In order to try to solve the problem, i tried instanciating the service by myself, but
Module not found: Error: Package path ./lib/graph/layouts/layout.service is not exported from package

What is the new behavior?
Lazily loads without any exception.

I think that it would be ok.
If I can, I'll change the providedIn: any to providedIn: root because the other one seems deprecated now.

Can we go ahead with this merge, layoutService needs to be global inject for lazy loading.
