nodes_dump.json adds invalid `paramtype2` value `4dir` causing exception

[Routhinator]

Just setting this up, added the latest version of the nodes_dump mod and it generate the dump. However starting a fullrender, I get the following error:

luanti@luanti:~/worlds/Treescape$ panorama --config panorama.config.toml fullrender
2025/08/28 10:50:17 INFO loading game description game=/var/games/luanti/data/.minetest/games/asuna mods=/var/games/luanti/data/.minetest/mods desc=/var/games/luanti/data/worlds/Treescape/nodes_dump.json
2025/08/28 10:50:17 ERROR unable to load game description error="invalid paramtype2: `4dir`"

Looking at the nodes_dump.json it appears that a large number (if not all) of the blocks have the exact paramtype2 value it's complaining about. Given it's being generated from nodes_dump that way - I presume this is a bug in that mod.

"paramtype2" : "4dir"

Full copy of the dump attached. This is with Luanti 5.14-dev

Panorama and nodes_dump are both latest master.

Looks like 4dir nodes were added as of 5.7+ so the problem actually lies in panorama as it does not have that type in it's support list yet.

Specifically here https://github.com/lord-server/panorama/blob/master/internal/game/node.go#L120

Cross referencing with https://github.com/luanti-org/luanti/blob/master/doc/lua_api.md

Appears the list is missing:

• 4dir
• color4dir

And the following seem deprecated

• waving
