Describe the bug
Moving dynamic lights source with enabled ModernFix mixin.perf.deduplicate_location=true causing lag spikes

This happens because CopyCats constructs new ResourceLocation very many times per tick at com.copycatsplus.copycats.compat.Mods.rl(), which shouldn't happen.

To Reproduce
Steps to reproduce the behavior:

1. Modlist:
   
2. Add newline to modernfix-mixins.properties

mixin.perf.deduplicate_location=true

3. Modify in betterf3.toml:

[general]
	always_show_tps = true

to see profiler graphics.
4. Take torch in hand and run. See lag spikes.

Desktop (please complete the following information):

• Minecraft Version: 1.19.2
• Mod Loader: Forge
• Mod Version: 2.1.4

I suggest to cache ResourceLocation. If it's new, call new ResourceLocation and add result to cache.
If it's in cache return from cache.

We have already cached the resource location in a test build. It should be out soon:tm: if theres nothing wrong with it
