Feature: Random look

### For which plugin is the feature?

FancyNpcs

### Describe your idea

Hey there! I've been using for a long time Typewriter plugin for NPCs but because of its massive issue related to time management I've been in need to switch to proceed custom NPCs a bit faster and I'm missing "liveliness" of NPCs in these means, that NPC is static unless player is close. Random look with some smoothing options and controllable angles will be a very nice addition to this plugin. Even setting `turn_to_player_reset_to_initial_direction` could be added per-NPCs basis to make them all more unique.

Start by reviewing FancyNpcs' existing NPC turning behavior and per-NPC configuration. Define how random looking, smoothing, controllable angles, and turn_to_player_reset_to_initial_direction should interact, then verify the behavior with NPCs in Minecraft.
