Retry downloads before failing.

[orbea]

Sometimes when using mangadex-dl it will trigger intermittent download errors where retrying one or more times will result in the download working.

I think it would be better if mangadex-dl would try the download a few times before deciding the download link did not work. I made this small hack which works sometimes, but someone that knows python could probably do better.

Seems PR https://github.com/frozenpandaman/mangadex-dl/pull/12 does this among other things.
