It's been some time since we rolled out a big update of SafariConverterLib:
https://github.com/AdguardTeam/SafariConverterLib/blob/v3.0.0/CHANGELOG.md

We need to bring this new version into AdGuard for iOS and the task can roughly be split into two parts:

• Use the new content blocking rules converter
• Use new WebExtension engine and JS library

This task is about part 2, i.e. bring the new web extension.
