Simplify the frame reading process and metadata extraction in `ffmpegdecoder.cpp` by reducing redundant code and improving variable initialization. Add a helper function in `ffmpegdecoder.h` to map FFmpeg field orders to Olive interlacing types, enhancing code clarity. Adjust the condition for interleaved write in `ffmpegencoder.cpp` for better handling.
