Subject: [PATCH] Add support for ignoring auto-created instances in sync
 process

- Introduced a new configuration for ignored class names in Config.lua to streamline the sync process by skipping instances that are auto-created by Roblox, such as TouchTransmitter and Camera.
- Updated PatchTree, applyPatch, and diff functions to utilize this configuration, enhancing efficiency by preventing unnecessary processing of these instances.
