[SnivyFilms]

Description

Describe the changes
Adds an event, plus patches for when a pickup is placed into the Pocket Dimension, as items have 3 different tiers which determines the chance of the pickup being either placed back onto the map or outright deleted

What is the current behavior? (You can also link to an open issue here)
Current behavior follows base game, with no ability to change it

What is the new behavior? (if this is a feature change)
Adds an event for pickups being placed into the pocket dimension

Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?)

This event and patch was taken from Exiled-Team Exiled before the huge drama, Yamato recommended. See: Exiled-Team/EXILED#2256

Types of changes
