* Add initial NAIP fetcher * Swap to Element84's EarthSearch API for NAIP STAC search and download * clip to bounds of aoi * Swap to Element84's EarthSearch API for NAIP STAC search and download * rename bands and remove dask chunking * Add DS_Store to .gitignore * restrict date range for naip test * Adjust timerange for tests * Add xarray to pyproj * Reduce aoi size * revert test to use tmp path * Update return types for tool to ensure state gets updated * Update unit test for compatibility with Command output from tool * Save image bytes directly to graph state for summarizer * add safeguard against large image sizes * remove print statement * Fix stac.load to work with MCP API by manually inserting band data into the extension * Remove deleted file * Add comment explaining workaround --------- Co-authored-by: lillythomas <lillyelizathomas@gmail.com> Co-authored-by: Daniel Wiesmann <yellowcap@users.noreply.github.com>
