Add NonFreeNet for Openreads v2.7.0

Openreads v2.7.0 introduced a feature to download covers from DuckDuckGo which is not libre hence NonFreeNet AF appropriate here.

NOTE: it's not yet build for F-Droid.

Checking the app I found that it's not automatic behaviour. The user need to click "Start" for it, but nothing mentioned about the source it connects to. So IMO the consent is not clear to ther user.

Contacted the dev on their matrix group & the dev has no issues flagging this version for AF. They said they"ll implement a better way to handle this & add proper consent for it.

Relevant upstream source from 2.7.0 milestone: https://github.com/mateusz-bak/openreads/pull/545

Please keep this issue open to make sure about the changes for the next version, thanks.
