Items Filter

Changes from (previously named Hopper Sorters) V.2:

• Items filters can now insert items into almost any kind of containers. They don't directly rely on hoppers anymore, hence the data pack's name change.
• Items filters no longer "spit out" items into hoppers, they now insert them correctly. meaning there is no risk of loosing items in case of overloading anymore.
• If a container below an items filter is already full, valid items that can't be passed are simply ignored.
• Instead of letting all matching stacks passing through it, items filters now have a 4 ticks transfer cooldown. It has been done to improve performances and make it more consistent with hoppers functioning. The transfer cooldown is also customizable, but can't be set to a value lower than 1 tick.
• The referring container's location is now indicated by an observer icon.
• The filtering mode button is now set on the opposite face, allowing you to change items filters mode even if you already set a referring container.
