feat: show visualiser

[sekwah41]

Need to either switch back over to using stained glass for spigot, or take a look at how to more, reliably send the debug packets.

Maybe via protocol lib and just make the feature depend on it? Wouldnt be a bad shout

See if https://github.com/MrMicky-FR/WorldEditSelectionVisualizer's code would be inspirational.

@rautamiekka they are using particles, which honestly is a really cool idea and may be good for older versions which don't support the feature I'm mentioning, though for this I'm specifically talking about

[sekwah41]

I think I'll take a look at a particle based visualiser at some point as a backup. Or might switch over to that solely if this is being a pain.

[sekwah41]

Actually, I am going to re-do this with particles; looking at the different versions, it looks like the way these debug packets are done varies too much between different versions of the game to reliably do nicely. I may re-visit it but its not worth the effort to have something that will likely break every few versions :(

[sekwah41]

What I'll do is add something like this back when I make the forge version as a client side optional mod.
