Problematic fastresume file prevents rest of export command

[W-Hamra]

So firstly, I'm not sure what is wrong with the fastresume file, but apparently, this is happening frequently (Seedbox company with thousands of instances).

What happens is that the tool runs fine most times, but for certain qbittorrent installs, it hiccups on a particular fastresume file, and then stops processing all other files and just stops the export claiming we're incorrectly using the tool 😃

I'll paste here a sample output:

root@server:/# qbt --config "${USERHOME}/.config/qbt/.qbt.toml" torrent export --source "${USERHOME}/.local/share/qBittorrent/BT_backup/" --export-dir /tmp/test/

As you can see in the redacted sample above. It found 38 torrents, it successfully processed 2 of them, then failed on the third.

Ideally, it should gracefully handle this error, perhaps throw an error about the file, then proceed to process the remaining 35 torrents.

Also, what the error means or if this fastresume is really problematic, I have no idea. Might it be a fileformat descrepancy with qbittorrent? I use 5.0.4.
