Fixed compilation errors and problems with Packages and Packagers

[SpacePython12]

There's a couple of classes here that were causing compilation errors because they were expecting Forge classes and interfaces, so I just put some placeholder code there so that it actually compiles.

Also, Package entities weren't being synced with the server correctly because of a missing super call (and it took me three days to figure that one out lol).

Finally, the Packager properly uses Fabric's transfer API now and doesn't void packages (or crash the game).

Thanks! Check some bugs in #1772.

EDIT: Please change the version number to accommodate 6.0.6.

Oh yeah, I saw that lol. I’ll fix it when I get the chance. I’ll also bump the version too

The rendering issues are gonna be harder to fix, it looks like an issue with Flywheel and Flywheel's documentation sucks

EDIT: On your thing, the mixer works fine. Boxes work fine, too.

Can confirm, Built against Java 17 and the build was successful and runs in game. Nice work @SpacePython12

I appreciate it, but there's a few problems.

Please don't bump the version number. That would be incorrect without a full merge from Forge.

The rendering issues are known with a planned fix.

Alright, I acknowledged your suggestions, @TropheusJ. Sorry, I'm new to the whole contributing to open source thing.

Thanks! For some reason, IThundxr wouldn't tell me that about the graphics issues. I requested to bump the version cuz there is one commit that states: Merge v6.0.6.

EDIT: Oh, it fails to build again.
