Improved Mars Detail Map (again)
Redid image and comparison pictures

-Improved Mars detail map
-Added mipmaps to Io's textures
-Improved Achilles detail map
-Improved Europa detail map

-Redid Mars from scratch. My previous attempts looked nice but stumbled up close, as they were still pretty blurry and used non-flat textures in some places. Now it uses much nicer textures and a 4k detail map, which really makes the gravel/rocks pop up close.
-Achilles grass textures no longer are blurry, it was a very overdone normal map so I just smoothed it out.
-Venus I added a better detail map, and improved sulfur transitions.
-Europa I added an icy detail map
-Io I added a better 4k detail map
