[Thanzo] Mrsat PMDG 777 Lights

This add-on provides updated lighting compatibility for the PMDG 777 series, including the 777W, 777ER, 777LR, and 777F. Adapted from the original MrSaturday530 mod, this version ensures functionality across all PMDG 777 models while retaining the originals integrity. A future release for MSFS 2024 is in development, and testers are sought prior to its launch.
