Improving stability and changing the voice of chats

1. Added new Particle Core and Radium optimization mods! Also, Sodium Exstras is back in the build instead of Sodium Exstra due to a strange conflict with Radium.

2. The DMC server for which this modpack is created has replaced Simple Voice Chat with Plasmo Voice, so I also replaced them in my modpack!

That's all the changes for now! I'm still waiting for CIT Resewn for Neoforge, or at least just for Forge so I can add it to the modpack, because it's still the only mod that is missing for the Neoforge version of the modpack!
