good first issue

Description

Basically, it's not uncommon for me to get an error when downloading/archiving a large channel. So when I try to restart the download, I end up redownloading everything--even the files I've already successfully downloaded.

It'd be great if we can add a flag that will allow a download operation to skip if a file with the same filename already exists in the export folder.

Research direction
Examine the main download logic in the repository's entry file (likely index.js) to locate where files are saved. Implement a check using `fs.existsSync` or `fs.promises.access` before initiating a download. Add a command line flag (e.g., ` skip existing`) using a library like yargs or commander. Update the README to document the new flag.
