Improvement

1. Change SceneNode.Attach to accept IEffectsManager instead of IRenderHost.

UI thread is still required to add generated sub graph back to the main graph which is associated with the Viewport. Example can be found here. (WPF.SharpDX/UWP/Core/WinUI)
2. Re-implement logging to use Microsoft.Extensions.Logging.Abstractions logging interface. To override the internal debug logger, set HelixToolkit.Logger.LogManager.Factory on app start up to provide your own logging implementation.
3. Due to logging change, minimum dot net version has been changed for all Helixtoolkit libraries.

   + .Net Framework 4.6.2 
   - .Net Framework 4.5
   + netstandard 2.0
   - netstandard 1.3
