Support for 7.1.4 surround (X.X.4 means height implantation for virtual surround)

 My purpose is increase the experience of Nahimic with height implantation for 3d games like Battlefield series  and For Honor. 
   İ came this request after reading Windows Spatial Sound For Headphones article in https://msdn.microsoft.com/en-us/library/windows/desktop/mt807491(v=vs.85).aspx they says that they can add more channel if they want to so i thougth Nahimic team can do it either.
  Thanks for reading& sorry for bad english.
