AYNZ Lae Nadzab BeyondATC Fix

This add-on updates the taxiway and parking layout of AYNZ Lae Nadzab airport in Papua New Guinea to ensure compatibility with BeyondATC. It enables the airport to load properly in BeyondATC and supports AI aircraft spawning when available. The modifications are based on Mountainair's AYNZ freeware scenery. This enhances operational functionality for users integrating both BeyondATC and the specific AYNZ scenery.
