`INSTALL` and `LOAD`
The `INSTALL` semantic in native embeddings of DuckDB is to fetch, decompress from `gzip` and store data in local disk.
The `LOAD` semantic in native embeddings of DuckDB is to (optionally) perform signature checks *and* dynamic load the binary with the main DuckDB binary.  
In DuckDB-Wasm, `INSTALL` is a no-op given there is no durable cross-session storage. The `LOAD` operation will fetch (and decompress on the fly), perform signature checks *and* dynamically load via the Emscripten implementation of `dlopen`.
