Immersive Fixes

A simple Immersive Engineering addon to backport critical bug fixes and minor content to 1.20.1. 

Note that I am not the one who patched these issues, BluSunrize (and the IE team at large) is. I merely backport the fixes to 1.20.1 with permission, so the IE dev team can pursue their goal of focusing on new versions of Minecraft. Don't be annoyed at Blu and co. for not implementing these fixes themselves, as back supporting is time consuming and difficult for a project of IE's scale.

Currently Supporting:
Fix: issue #5906: Fluids no longer destroy multiblocks.

Fix: issue #6149: Arc Furnaces give the correct percentage of secondary outputs (was previously inverted).

Fix: issue #6305: Coke Oven Exploit

Fix: issues #4917, #5440, #5909, #5933, and #6203 about logic errors with the Diesel Generator. Diesel Generators now don't confuse water for fuel, don't run infinitely, properly consume the right amount of fuel, and more. Read these issues on IE's repo for detail (or check the issue on my repo to find hyperlinks to each of these issues).

Have some features you'd like to see in 1.20.1? Please let me know via my discord [here](https://discord.gg/mZUjrWK6NF).
