* This function can be overridden by mods to change the leave message.
* `core.hash_node_position(pos)`: returns a 48-bit integer
* `pos`: table {x=number, y=number, z=number},
* Gives a unique hash number for a node position (16+16+16=48bit)
* Gives a unique numeric encoding for a node position (16+16+16=48bit)
* Despite the name, this is not a hash function (so it doesn't mix or produce collisions).
* `core.get_position_from_hash(hash)`: returns a position
* Inverse transform of `core.hash_node_position`
* `core.get_item_group(name, group)`: returns a rating
