- Add custom excel_url driver for reading Excel files from URLs - Uses simplecache for disk caching - Add GCB 2025 and GCB 2021 from ICOS-CP data portal Note: intake v2 has native Excel support via PandasExcel reader, but the YAML format is complex and not compatible with existing catalogs. The custom driver provides a simpler solution for YAML-based catalogs.
