added DotRecast to Library C# Geometry

- https://github.com/ikpil/DotRecast

DotRecast is a port of Recast & Detour, a navigation mesh toolset for games, to the C# language. It is useful for game developers who want to use C# servers, C# projects, or Unity3D for their games.

DotRecast allows you to generate and use navigation meshes for pathfinding and spatial reasoning in your game world. You can also customize the navmesh generation and runtime navigation systems to suit your specific game’s needs.
