v2.0.0 Beta 1

It's been a bit since a massive update, but I'm here with a giant update! Let's get into the changes! Please note that this beta only contains the new updated/replaced RPC system. In terms of "features", this beta doesn't have anything other than non-advanced mode being able to display username and player head if that's what you want! There's a lot more features/changes I want to make for this version, but I felt like getting this out as soon as I could would be the better move in order to test for compatibility issues!

Completely updated/replaced old Discord RPC system with a new one. The goal was to hopefully allow for better performance and support for more platforms (Maybe now it'll work on mac!)
I've only tested this on 1.21.4, but it may work on other 1.21 versions, I just haven't tested this yet.
