ThePullerCell's Furnace Refuelers

This is my second public data-pack! This datapack allows Furnace Minecarts to refuel from lightning strikes.

To use this datapack:
- Place two strings above a rail
- Place a Redstone Lamp above the second string
- Place an upwards-facing Lightning Rod (must not be waterlogged!)
- You are done. Once a furnace minecart passes this machine and there is a lightning rod, it will refuel.

I tried to make a balanced datapack so it cannot refuel always.

This data pack was only tested in 1.21.5, and it was not tested to work on servers. Use on servers at your own risk. It probably works with all 1.21 versions, though it is unlikely to work in 1.21.9 and higher.
