Tile flags appear both in labyrinth map data, as part of LabInfo blocks, and in 2d map icon data, where they are hardwired to specific map icons. They appear similar in structure to Ambermoon tile flags (https://github.com/Pyrdacor/Ambermoon/blob/master/FileSpecs/Enumerations/TileFlags.md).
The interpretations below are mostly observational and require full validation.
