refactor: replace linc_luajit with hxluajit

[moxie-coder]

This will need EXTENSIVE testing btw to make sure most mods still work and such, because despite it still being luaJIT, it's an different implementation

[moxie-coder]

I've also heard this was better over linc_luajit too, and this is part of how I'm hoping to fix compatibility with 0.6 mods, since I do have an build of my own mod, that uses hxlua with 0.6.3

same as the first lua refactor:
works as intended, but runHaxeCode is just. dead

So no difference essentially, gotcha then

        public static function addCallback(l:State, name:String, func:Dynamic)
        {
-               // PsychLua expects the function to be null for local callbacks, too lazy to do something about that
-               if (Type.typeof(func) != TFunction || func == null)
-                       return;
-
-               callbacks.set(name, func);
+               // PsychLua expects the function to be null for local callbacks so if func is not TFunction we don't add the callback here
+               if (Type.typeof(func) == TFunction)
+                       callbacks.set(name, func);

                Lua.pushstring(l, name);
                Lua.pushcclosure(l, cpp.Callable.fromStaticFunction(handleCallback), 1);

@JordanSantiagoYT try it now I guess

[moxie-coder]

I would like to say that some haxe errors are from the compilation error, I don't often comment much and just use the engine on my mods when I'm not doing work or touching grass on beautiful days but it that time it failed to compile 4 times. After it was recompiled the 5th time, a couple things slightly broke so if you gain a lot of more haxe errors. I'll link the last build that worked. Though it's before 48 so you would have to reoptimize the code and reimplement custom variables so ofc I'll be waiting but I dought it be a big deal unless something big planned doesn't work after multiple attempts...

What does this have to do with the PR?

[moxie-coder]

I might just merge this just because of two reasons, as I've said before, linc_luajit isn't really maintained anymore, and it's very old. And hxluajit is made by the same guy who's made just about almost all the libs this engine uses now (hxvlc, hxdiscord_rpc, hxnativefiledialog etc.) while also hearing good things about this too. Plus with HScript being broken and shit, it probably can't be made worse then it already is with this
