v5.7.0

✨ Features and improvements

• feat: add opt-in Prometheus metrics endpoint (#2211) (by navidnabavi)
• feat: allow the data decorator to be asynchronous (#2352) (by acalcutt)
• Updates Maplibre-gl-js to v6 and maplibre-gl-inspect to v1.9.0. maplibre-gl-js v6 is ESM-only, so the viewer and data templates now load it as an ES module via an import map, and the elevation control is now an ES module. maplibre-gl-js v6 requires WebGL2; the viewer falls back to the raster (Leaflet) view without it (#2360) (by acalcutt)
