Integrate svelte-maplibre components

[Riezebos]

Evidence is an amazing tool, especially with the new Universal SQL. In my opinion, it could use some more map visualisations. There is a svelte library for this that looks quite nice: https://github.com/dimfeld/svelte-maplibre

Here are some example maps: https://svelte-maplibre.vercel.app/examples/basic

Would it be possible to integrate these into Evidence Labs?

I don't know exactly how it can work, but for example if we'd like to visualise a geometry column in DuckDB:

• Create a query with COPY INTO something.geojson: https://duckdb.org/docs/extensions/spatial.html#spatial-copy-functions
• Export the data to a buffer similar to: https://duckdb.org/docs/api/wasm/query#export-parquet
• Use that buffer as input similar to states in this line: https://github.com/dimfeld/svelte-maplibre/blob/master/src/routes/examples/geojson_polygon/%2Bpage.svelte#L10

My background is more in Python/SQL, but I've used Svelte a little bit. Maybe I can help?
