Add initial implementations for encoder handling and conversion logic

Introduce encoder modules for various codecs and formats (e.g., h264_nvenc, libx264, libmp3lame). Add `Convertor` logic to retrieve supported formats via FFmpeg utilities and manage encoders for audio, video, and image processing.
