All features with indoor=* may not be polygons

[PanierAvide]

Hello,

I had a bug report on OsmInEdit (indoor editor) due to a bug of rendering, which might happen partially due to this library. In fact, a feature having highway=corridor + indoor=yes tags is considered by this library as a polygon. However, highway features are most of the time polygons if they have a area=yes tag. And adding indoor=yes tag on highway feature is relatively common, and doesn't mean they become areas. I'm not sure of what should be the rule in the JSON file to say that :

• Features with indoor tag are polygons
• Except when they have a highway tag that make them a line

Best regards.

Unfortunately, the simple heuristic used here doesn't allow to invalidate matches based on presence of further tags. 🤔
