WidgetFeedStorage

Platform filesystem operations for the generation-versioned export. Implement it yourself for a custom location; the defaults are AndroidWidgetFeedStorage and IosWidgetFeedStorage.

Contract for readGenerationCandidates order: pointer current, then pointer previous in order, then every other non-temp generation directory sorted descending by id. Unsafe ids and directories without feed.json are skipped. Never throws for corrupt files.
