Initialize DuckLake credentials by passing ducklake name, catalog and storage configuration.

Arguments:

• ducklake_name - str This value is mainly used as ATTACH name for the ducklake database and as names for catalog and storage files if not configured explicitly. If omitted, ducklake name is derived from destination name or pipeline name.
• catalog - Either a connection string (for example, "sqlite:///catalog.sqlite", "duckdb:///catalog.duckdb", or "postgres://loader:loader@localhost:5432/dlt_data") or a ConnectionStringCredentials instance. If omitted, will default the catalog to a local sqlite database whose filename is derived from the name_or_conn_str argument.
• storage - Either a storage URL string (for example, "file://...", "s3://bucket/prefix") or a FilesystemConfiguration instance. If omitted, it will create a folder for data with name derived from the name_or_conn_str argument.
