SDKMESH updated to load models using legacy DEC3N compressed normals #41

There is no direct DXGI equivalent to the legacy Direct3D 9 vertex format D3DDECLTYPE_DEC3N. It's a signed 10:10:10 normalized format. Some legacy DirectX SDK samples for DX10 / DX 11 just treat it as DXGI_FORMAT_R10G10B10A2_UNORM which kind of works.

This update uses that hack for DirectXTK, but emits a warning in debug builds.
