* refactoring result codes - Add a main enum who can handle some orphalin result codes and the default `ResultCode.Success` one. - Add sub-enum by services when it's needed. - Remove some empty line. - Recast all service calls to ResultCode. - Remove some unneeded static declaration. - Delete unused `NvHelper` class. * NvResult is back * Fix
