shareware mod

This is a compilation mod that joins a couple of minecraft speedrunning mods

• atum (generates new world after leaving one)
• legacy planar fog (pretends GL_NV_fog_distance is unavailable for more exploitable fog)
• force port (open to lan always 25565)

with some others

• voyager (java 11+ concurrentmodificationexception fix)
• motiono (disables sprinting fov changing)
• legacy debug pause (backports the f3 + esc pausing from 1.14+)

the ability to make 3d shareware fabric mods is now possible because of the mappings i generated from fabric's ancient official -> named ones, so if any devs see this, here ya go :)

todo:

• it deletes world every time you exit, need to make that conditional on if atum is running and also store if atum was running at quit and delete world conditionally on startup
• enable multiplayer :eyes:?
• make atum file writing a randomaccess file so it's not creating a new filewriter object every write
