This is an adapted version. Changes made (2026-09-28; the 2026 Q1 and
2025 Q4 mobile files were added later the same day, in the same way):

  - Added a geometry column (GeoParquet, WKB, OGC:CRS84) parsed from the
    original tile column, and a bbox column (xmin, ymin, xmax, ymax).
  - Sorted rows by quadkey and rewrote them in row groups of 20,480 rows,
    so that small areas can be read with HTTP range requests.
  - No original value was changed and no row was removed. See README.md.
