Overhaul to enemy AI, mainly visual detection but tweaks for sound, gun accuracy, and combat movement. Recent update added spawn controls.

Main change
Enemies now have a visual detection meter that needs to fill before they "see" the player. The following factors are taken into consideration when filling the meter:

• Weather
• Time of Day
• Distance to Player
• View Radius
• Movement speed of player / crouch status / submerged status
• Flashlight on at nigh/dawn/dusk
• Height of enemy relative to player
• Optic on enemy weapon
• Last known location distance

Factors affecting enemy hearing:

• Weather

Factors affecting enemy accuracy (Spread is now based on a cone in degrees so it naturally increases over distance):

• Enemy movement speed
• Enemy gun type
• Enemy gun optic type
• Enemy type
• Full auto
• Player move speed

Enemy Decision Making

• Enemies will now commonly stop to shoot if they're at range, as it increases their accuracy.
• Enemies will switch to full auto the closer they are to the player.

I'm leaving in all the MCM options I used for debugging. I'd recommend to only change the 3 options labelled "MAIN" at the top. If the AI starts to act weird, set everything back to default.
Anybody is free to modify this mod further. I made it mainly for myself and uploading in case anybody else wants to use it. I only plan to maintain it if I have time, and until the dev officially revamps AI later this year.
