Improved Barnacle NPCs

This addon works fine on my end as of December 2023, if you have problems I'm going to need more info than just "doesn't work", there are settings as well you may just need to tweak to get what you want.
Remember using Barnacles for NPC Battles?
I don't.
This intends to change this by introducing the fully-adjustable ability for Barnacles to spread and infest interiors over time, along with other related quality-of-life options. In total, this adds :

• A customizable barnacle growth system, where they will gradually (or quickly, it's editable!) spawn new barnacles around them over time.
  
  
• A slider to set a timer for Barnacle corpses to be removed instead of remaining permanently.
  
  
• The option to lower the amount of gibs barnacles drop on death by default.
  
  
• The option for barnacles to eat players, instead of delivering a fatal blow.
  
  
• Customizable health and damage multipliers.
  
  
• The option for melee weapons to not insta-kill barnacles.

This is all adjustable in the Utilities menu, under OnTheMatter titled "Barnacle Settings", which contains detailed explanations for each Slider and Checkbox, which include options such as spawn padding, max population, min and max spawn distance, max-height-offset, etc. Convars start with "sfad_barnaclehive_" for those applicable. This just modifies the base npc, it doesn't add any new ones.
I decided to make this after realizing that the base npc really isn't worth using most of the time. Anyways, I hope you like it!

Type "hl2_episodic 1" into the console if you want barnacles to eat headcrabs off of zombies, just be aware that it will likely cause some other obscure issues, especially if you don't have half life 2/its episodes mounted.
