Gjum/SnitchMod

AI Summary: Refactor the Java code in the Snitch Mod project to replace all explicit `null` checks with Java's `Optional` class for improved code clarity and null safety. This involves iterating through the codebase and replacing instances where `null` is explicitly assigned or checked with the appropriate `Optional` methods.

AI Summary: The task is to fix a bug in the SnitchMod Minecraft mod where the 'maybe refreshed' status for snitches only updates when snitch rendering is enabled. The fix requires modifying the Renderer.java file to ensure the refresh status is updated regardless of whether rendering is active.
