Lennox.LibYuvSharp 2.0.0

2.0.0 moves to the latest libyuv version. * JPEG/MJPEG decoding is now included using statically linked libjpeg-turbo 3.2.0. For full-range JPEG RGB output, use MJPGToI420 followed by J420ToARGB; upstream MJPGToARGB uses a limited-range conversion. * M420ToI420, M420ToARGB, GetARGBBlend, ARGBToG, and SetUseReferenceImpl were removed upstream. Convert M420 input to a supported layout before calling libyuv. ARGBToJ400 is available for full-range grayscale conversion. * RotateUV90, RotateUV180, RotateUV270, TransposeUV, and NV21ToNV12 remain available as aliases to their current native equivalents. * ScalePlane and ScalePlane_16 now return the native status code (int). Native size_t parameters use UIntPtr; native char* parameters use sbyte*, and signed 8-bit data uses sbyte* rather than byte*. * Matrix APIs accept opaque void* pointers to native YuvConstants or ArgbConstants structures. These must refer to valid native structures; their SIMD layout is platform specific.
