Support maplibre v6

MapLibre 6 is ESM-only and drops its default export, so internal imports switched to namespace imports. Vite users must import maplibre-gl/dist/maplibre-gl-worker.mjs?worker&url and pass the result to maplibregl.setWorkerUrl() before creating a map. This can be done in a <script module> tag in your Map component or anywhere else in your application that loads before it.

Breaking changes to this library's own API:

• StyleLoadEvent is now an alias for MapLibre's MapStyleLoadEvent. It no longer has map and style properties — those never existed at runtime — and carries target instead.
• The zoomstart, zoom, zoomend, pitch and rotate handlers on MapLibre and MapEvents now receive MapMovementEvent. They were previously typed as MapLibreZoomEvent, which MapLibre 6 renamed to MapBoxZoomEvent and which only ever described box-zoom events.
• The data handler on MapLibre and MapEvents now receives MapSourceDataEvent | MapStyleDataEvent; MapDataEvent was removed from MapLibre.
• Popup's onhover prop was removed. It listened for a hover event that MapLibre's Popup never fires, so it never ran. Use openOn="hover" with onopen.
• Layer's paint and layout props are typed as AllPaintProperties / AllLayoutProperties instead of object, following MapLibre 6's typed setPaintProperty / setLayoutProperty.
• RasterDEMTileSource's encoding prop is typed as RasterDEMSourceSpecification['encoding'], since MapLibre does not export DEMEncoding.

New in this release:

• MapLibre accepts a zoomLevelsToOverscale prop. MapLibre 6 changed this option's default to 4, which splits vector tiles above a source's maxzoom rather than overscaling them; that improves labeling but slightly alters rendering and queryRenderedFeatures results. Pass null to overscale at every zoom level, as MapLibre 5 did.
