[twitter] prevent downloading of smaller images in case of 504 errors

[Doofy420]

Like the title says, gallery-dl falls back to progressively smaller images until it succeeds. Is there a setting to disable this behavior? Like, just skip the image after x amount of retries. I find that manually retrying the download works most of the time.

@mikf Could we get a confirmation on how "fallback": false would work? Does it skip that one problematic image or does it skip the user profile entirely? I should probably test this more but it resulted in the latter for one of my ripped profiles

Each Twitter image has several "fallback" URLs, the "progressively smaller images", in case the main download fails (#237). "fallback": true allows gallery-dl to use them and you get those Trying fallback URL #N logging entries. "fallback": false immediately goes to Failed to download X and doesn't consider using fallback URLs.
It only affects the download process of individual files and should not result in an entire user profile getting skipped.

Alright, thanks for clarifying. It might have been the same issue as #1792 (I was using --abort 1)
