Remove default rsmpeg to prevent downloading multiple versions

- Removed default rsmpeg dependency
- Each platform now only downloads its specific rsmpeg version
- Linux: 0.14.2 (FFmpeg 6.1)
- macOS: 0.18.0 (FFmpeg 8.0)
- Windows: 0.17.0 (FFmpeg 7.1)
- Removed invalid feature flags (ffmpeg6, ffmpeg7_1, ffmpeg8)
