[Devlog] Improving the Instant Renderer interface

I simplified the interface, hid some settings and made IR more automated, added Global Settings. Now the IR interface is a Window and not a GameObject component, now you no longer need to find the IR on the stage. It is also possible to delete a prototype and it will be removed from all scenes where it was added, the prototype settings are global for each scene. In addition to the interface, I accelerated streaming with IR, conducted tests where I compared the streaming speed with Unity Terrain Tree and with IR, IR objects allow you to load the scene much faster. Also spawn speed increased All my tools are completely free, but only for users of my Discord server, just PM me: https://discord.gg/fVAmyXs8GH (Join us for more info, updates, if you experience any issues or if you just want to say hi!)
