Do not overwrite already existing ZIM by default, stop immediately

I restarted docker run -v /output:/output ghcr.io/openzim/zimit zimit --url https://flibusta.is --name flibusta - is it using previously saved zim?

On the second run I pressed Ctrl-C and it removed my zim from the first run!

Indeed the ZIM filename being constructed from the url and the current month, if you run twice the same exact command, it will overwrite your previous ZIM. And if you cancel during the second run, then you end up with nothing.

I think the reasonable way forward is a --overwrite option that if not present halts the run should the target ZIM file already exist.

Good point!

And obviously this needs to be checked as soon as possible, at least before running the crawler
