feat: Add Python script to convert MKV files to MP4 with resizing

This commit introduces a Python script that enables the conversion of MKV files to MP4 format with the libx264 codec and rescales the size by half for both length and width. The script utilizes the subprocess module to execute FFmpeg commands, ensuring efficient conversion. Users can specify input and output folders for seamless batch processing of MKV files.
