(Partial) Cadmium 0.1.0 for Minecraft 1.16.2 - 1.16.4

NOTE: There's a known issue, #1, where this will prevent the game starting under some conditions. If you encounter this issue I recommend you try LazyDFU instead of this Cadmium.

Here's my fork of JellySquid's Cadmium for production environments, which I've ported to 1.16.4.
Cadmium makes the game boot faster by optimizing DataFixerUpper's initialization.

This version doesn't have the full set of DFU optimizations that JellySquid's original version has, but it still has enough optimizations to reduce the game's startup time significantly (depending on your environment, probably most helpful for ZGC users).
