Preserve raylib types

Removed "Cricle" and "Line" structs (and their extension methods) to conserve only raylib types.

Added "Dimensions" property to "Texture2D"
Added another "Load" overload for the "Texture2D" extensions (load from memory)

New overloads for the "LoadFileData" and "SaveFileData" methods
