add-on idea: better storage barrels

[ShadowCreator250]

• like in FTB
• like the datapack from this dude I commented the video (watch later playlist SC250)
• log with an item_frame in front
• place item (stackable) in item_frame
• lock item in item_frame with custom item (get 1 of the item back)
• all items that are nearby item_frame and matches item in item_frame are sucked in (added to item count in barrel)
• turning item in item frame releases 1 item out of barrel (must be resetted)
• shift turning releases 1 stack (if available)
• taking the item out of item_frame releases all remaining items and frees the barrel
• item in item frame is renamed after current item count in barrel (test this!)
  (all must be tested, I don't know if this works)
  (is there a scoreboard for turning an item in a item frame?)
