2D Texture Atlas importer plugin for other texture pack tools

Load packed atlas texture to filesystem and can be used in godot.

Cureent support tools and formats

• TexturePacker : Generic XML
• TexturePacker : JSON hash
• Attila : JSON
• Kenney Spritesheet : Atlas from Kenney assets

As godot doesn't support rotated atlas, so don't rotate sprites when you pack pictures with above tools or you have to rotate them back manually.
