Combine Spyglass and longguns

I'd like to suggest a feature that lets us equip our spyglass as a scope on a rifle or other longun. Alternately bring in a longgun like a rifle that is crafted with an attached scope that functions like the spyglass tool.

The main reason I want this to save space on the hotbar just like using an axepick saves having to constantly swap between two tools when moving between combat and different types of gathering.
