[ATS] Starlit Sky Mod 1.33.x

Are you bored with a night drive? StarlitSkyMod(SSM) replaces the night sky textures with high resolution alternatives made from real astrophotography (no other textures and sii file are affected, it is only night sky textures) Tested on ATA ver1.33 but SSM only replaces the textures, so it may work with other versions I hope you enjoy night drive Source of photo: NASA(https://www.nasa.gov/) NASA Image and Video Library(https://images.nasa.gov/) NOAO/AURA/NSF(https://www.noao.edu/)
