mediadecode-ffmpeg 0.2.0

FFmpeg adapter for the `mediadecode` abstraction layer — implements its `VideoAdapter` / `AudioAdapter` / `SubtitleAdapter` traits and the matching push-style decoder traits, with hardware-acceleration auto-probe across VideoToolbox / VAAPI / NVDEC / D3D11VA and software fallback via ffmpeg-next.
