Michael Fabian 'Xaymar' Dirks a4b3131c50 project: Version 0.2.0 
* Completely rewrote most of the plugin from scratch to unify the encoder class into one file, resulting in much lower code and size overhead and all optimizations being in effect for all encoders.
* Removed old ProRes encoder interface as it has been replaced with the new interface.
* Added support for NVidias H.264/AVC NVENC Encoder with all options, including the capability for YUV 4:4:4 encoding. It is slightly faster and less CPU intensive than the version included with OBS Studio.
* Added support for NVidias H.265/HEVC NVENC Encoder with all options. This finally brings the HEVC market to NVidia people in addition to the AMD people that have already been able to use this with enc-amf.
