Retro AI traffic for Norway

This add-on introduces retro AI air traffic for Norway and parts of Scandinavia in Microsoft Flight Simulator. It requires AIG base models and repaints, with FShud used to inject traffic into the simulator. The package was initially designed as an enhancement for ENFB Fornebu scenery but can be used independently. Compatibility is intended for MSFS2024, with possible support for MSFS2020.
