GLFW error during init

ever get that dreaded GLFW error during init, and notice that instead of telling you why the error occurs, it prints a randomass number? that's cause mojang forgot pointers exist. this mod just contains a small mixin to make that error handling work properly, so you can actually see why your game is crashing. particularly useful if you're trying to figure out wayland support on glfw.

supports pretty much every relevant minecraft version? if the mixin doesn't apply to a version, odds are the problem isn't there in the first place.
