Mesh Dumper REPL command

[kiwidoggie]

Currently when issuing the dump mesh command, it does not find the implementation in RimeLib.Mesh.Frostbite2_0 for whatever reason.

The options for exporting to text, GlTf, and BlenderScript also need to be implemented.

The work being completed is located in PR: #13

Currently this is using IceBloc's code, which doesn't seem to work properly. Will need to pull out code from previous RimeLib extraction which extracts all LODs properly

Pending removal of GLTF because the library is broken and does not want to work correctly. Adding SharpGLTF.Core as a project dependency from NuGet, copying the dll to /bin folder. Nothing works always returns

Could not load file or assembly 'SharpGLTF.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6f8b67557d279fe6'. The system cannot find the file specified.

Screw it, done wasting time with it.

Will need to investigate using FBX, Collada for import/export.
