I made this because I kept running into issues and limitations when trying to embed DuckDB in Go applications: because DuckDB and its extensions do their own I/O in C++ land, integrating with the rest of my applications to get authentication or instrumentation working was really challenging. With go-duckfs, all this happens on the Go side, it's like a sandbox for all I/O that happen during queries.

It's kind of like https://duckdb.org/docs/stable/guides/python/filesystems but for Go. I think it'll be useful to anyone who is using DuckDB in a Go application, let me know!
