Lumi Lighting Engine Optimizer

A full replacement of the Minecraft lighting engine with an extendable API, shipping with [Phosphor](https://github.com/GTMEGA/Lumi/blob/master/src/main/java/com/falsepattern/lumi/internal/lighting/phosphor/PhosphorLightingEngine.java) as a reference implementation. ## Dependencies - [ChunkAPI 0.5.0+](https://modrinth.com/mod/chunkapi) - [FalsePatternLib 1.2.0+](https://modrinth.com/mod/fplib) - [UniMixins 0.1.11+](https://modrinth.com/mod/unimixins) ## Performance The main performance improvement comes from the fact that the lighting engine is evaluated "lazily", thus it is able to batch more lighting updates into a single pass. Here are some simple to understand values, generated via profiling a pre-set test case: Test Case - World Type: Default - World Seed: 123 - Game Mode: Creative - Render Distance: 16 Profiler is started right before clicking Create New World, and stopped after 10 seconds of flying in a straight line in creative mode. Without Lumi, the active server time spent in lighting engine is 34% of the total active server time (not counting when the server thread is sleeping). With Lumi, this fraction goes down to 13%, or an approximately 2.5x performance increase over vanilla. Flame Graphs Horizontal axis is time, vertical axis is the call stack. The blue highlighted parts are calls to the lighting engine update method.   ## Incompatibilities - [ArchaicFix](https://modrinth.com/mod/archaicfix): Config Change Needed - As both mods replace the same parts of code, naturally you will need to set `enablePhosphor` to `false` in the ArchaicFix config. - [CoreTweaks](https://github.com/makamys/CoreTweaks): Config Change Needed - The `fix_heightmap_range` feature is already implemented in Lumi's lighting engine. Set it to `false` in the CoreTweaks config. Both of these configs will be automatically modified by Lumi automatically when you launch the game, so you shouldn't even need to edit the config files manually. ## Authors - [FalsePattern](https://github.com/FalsePattern) - [Ven](https://github.com/basdxz) ## Credits - [embeddedt](https://github.com/embeddedt) - The initial port of [Phosphor into 1.7.10](https://github.com/embeddedt/ArchaicFix/blob/main/src/main/java/org/embeddedt/archaicfix/lighting/world/lighting/LightingEngine.java) - [CaffeineMC](https://github.com/CaffeineMC) - Creating the original [Phosphor](https://github.com/CaffeineMC/phosphor-fabric)
