Currently the module AI contains the classes for all supported AI providers.
If a Node app wants to use one AI providers, it also has to import the packages from the other AI providers,
as they are imported from the same module.
By splitting up the AI providers specific classes into separate modules
plus a base AI providers module for common AI classes,
only the npm packages of the used AI provider have to be added to a project.
This also requires removing AI providers specific references from the base AI module.
