String Duper Revived

## Description **Bringing back the string duper functionality from previous Minecraft versions, this mod adds a block with some additional quality of life to let players create their own string-based economy once again.**  ## Recipe and additional information  Recipe uses any trap door type. Also note, that's a dropper in the center. Power with a redstone signal to turn on. Placing a piece of wool (of any normal/dyed variant) adjacent to the String Duper will silence the ticking noise we've all come to love in case it's not for you. Additionally, placing a solid block in front of the String Duper will cause it to turn off. If you find any bugs, don't hesitate to let me know! **Feel entirely free to use this mod in your private or public modpacks. No need to ask for permission.**
