Access wideners

[Gamebuster19901]

Add access wideners to wilderforge. Some classes would be better off if they were changed from package private to public instead of using access mixins.

Access wideners seem to be deeply integrated into loom. I'm sure there's a way to integrate access wideners into WW, but I want to get the modding api released as soon as possible, so I'm postponing its inclusion.

Pull requests which implement this feature are welcome.

Looks like there's a PR upstream that would allow provider to include access wideners. See FabricMC/fabric-loader#1049

Still would require changes to WW to make the access widener change visible at compile time.

Another upstream PR: FabricMC/fabric-loader#1055

Still would require changes to WW to make the access widener change visible at compile time.

[Gamebuster19901]

This should actually be possible now: FabricMC/fabric-loader#1056

I think these might actually just work out of the box now in 6.0.0.0+ because fabric loader and game provider have been updated. Needs testing.
