Stop ignoring SW based ZIM files (from the library)

[kelson42]

Once Zimit files are confirmed properly working on iOS or macOS we should stop „ignoring“ SW based file.

Why? zimit SW files are not and will not be supported. zimit2 files dont have the SW metadata so nothing has to be done.

IMO this ticket should be closed.

@rgaudin There won't be anymore such files (with SW) in a few months. This is the goal at least. Once achieved, this issue will be implemented.

It's not clear if we will or won't have ZIM based on SW in the future. Considering the current code related to SW has no real impact, we can keep it without other consequences.
