Mosaic duckdb-server API Support

The Mosaic duckdb-server supports WebSocket connections with simple API.

You can use the generated signed WebSocket URL with Mosaic "clients" for using BoilingData instead of a local duckdb-server.

Since there is no requestId (or similar) key to map requests and responses, only one request should be sent at a time. Also, as there is no batch fragment identifiers, multiple received messages should be assumed to belong to the same response set.
