access=no winds up as construction lane

See https://www.openstreetmap.org/way/745724293 in `leeds_cycleway` for one example, but I think I've spotted others.

In this one case, `psv=designated` should map to a bus lane. We only look for `psv=yes` today.

The issue points to a specific OSM way (745724293) in the `leeds_cycleway` dataset. Look for code that maps OSM tags like `psv=yes` to lane types. The bug is that `psv=designated` is not recognized as a bus lane. Find where lane mapping logic is defined, likely in a module handling OSM tag conversion. Test the fix by running the conversion on the provided example and verifying the lane type changes.
