Just to say something about the change in general: all reflections are now using MethodHandles which should be much faster as they use generated code internally. Thats also part of the reason why I removed the structure compiler, but the more relevant one is that there are not much packets which have public fields so that they can be accessed via the compiled structure modifer, and defining them as "nest mates" in the packet class directly does not work as the class loader of the packet classes has no access to the protocol lib internal classes (changing some stuff so that it is possible would be doable, but MethodHandles should be enough).

Just to say it: when exploding 1000 TNT blocks - reading the x, y, z values from the explosion packet is less heavy than sending a message to the player:

I also removed the class accessors for pre-1.8 classes (as injecting into the netty pipeline is not even a thing anymore), and most of the duplicated reflection code (like access via Accessors, FieldUtils, MethodUtils, Fuzzy etc.).

This change is tested on various minecraft versions between 1.8 and 1.18

great work, this is really impressive stuff!

looks like there's a small merge conflict in EnumWrappersTest but otherwise i think it's good to go?

Will fix that tomorrow 👍
