New ground textures

Update added install guide for oxys maps should be similar for other maps. also added a new set of textures. Cleaned up the textures fixed most of the problems texture 2 is completely new as I didn't like the previous version.

Here are improved ground textures made from scratch with real photos that I spent a long time collecting. I plan on adding more to the pack but just want to show you all what I have so far I would love feedback on what you would like. So far there are two new textures in the pack they are completely different.

In the zip, there are the textures and install instructions.
