Make zooming possible only when certain item is in the inventory.

Add optional check to make zooming work only when a configurable (enter ID) item is present in the inventory. Firstly I wanted something like a spyglass but realized I can do the item by myself.

Hmm this would normally require something like cloth config and adding it to this mod wouldn't really make sense. However I will look into parsing the item manually.

I'm not planning on adding an item requirement, thanks for the suggestion though!
