Support DuckDB, Rasterio, and TiTiler

[jtbaker]

These are already built/supported with Pyodide, so hopefully not too much of a lift to get it supported in the platform

Supporting them would allow to have a serverless cloud optimized geotiff raster tile server in an all Cloudflare context when combined with R2. The architecture (using AWS Lambda) is outlined here: https://kylebarron.dev/blog/cog-mosaic/overview
