Vertex colors are not converted

[JR-Morgan]

We never implemented support for converting meshes with Vertex Colours.
Mesh to native conversion ignores vertex colors which maybe useful to convert.

speckle-unreal/Source/SpeckleUnreal/Private/Conversion/Converters/StaticMeshConverter.cpp

Lines 280 to 289 in dcc14bf

	FVertexInstanceID VertexInstance = StaticMeshDescription->CreateVertexInstance(Vert);
	VertexInstances.Add(VertexInstance);
	if(SpeckleMesh->TextureCoordinates.Num() > VertIndex)
	StaticMeshDescription->SetVertexInstanceUV(VertexInstance, SpeckleMesh->TextureCoordinates[VertIndex]);
	//if(SpeckleMesh->VertexColors.Num() > VertIndex)
	// //TODO set vertex colors
	}
