Feature request name
Post-client-resource-load loader for scripts

Feature request description
I would like a way to run CraftTweaker scripts that can modify client resources like textures, models, and fonts. This loader would need to run after resource loads including reloading and changing the texture pack.

Feature request reason
I am currently porting my "tips" mod to 1.16.3. I've rewritten my data system to pull information from resource packs. I would like to extend support to CraftTweaker for things like adding, removing, and replacing tips.

Feature request dependencies
This feature request would require a new loader that is specifically handled on client resource reload, or an alternative approach that would allow executing the scripts after the resource data has been loaded.

**Game Version
1.16.3

Is this something that has enough usecases to be added to CraftTweaker?
Or is this a niche case where creating and loading the loader on your end would be better?
