Paper cross server player data syncing using redis and OpenInv | Provided without support nor warranty! (See point 15. in GPLv3 license) So do not use this if you can't support it yourself/don't have a support arrangement with me!
Updated the dependencies to the newest (1.20.6) version.
Most importantly is OpenInv with a change in its public API, where "retainPlayer" is now marked for removal.
I know the way I aggressively pushed everything to the newest versions probably means loading this version on older Spigot/Paper versions doesn't work, but since there is version indifferent reflection, loading it in the api defined 1.13 could have been broken anyway.
