Adds Sentinel-1_GCP_Geolocation.ipynb demonstrating GCP-based geolocation for Sentinel-1 GRD and SLC products using the EOPFZARR GDAL driver. - GCP extraction from conditions/gcp/ arrays (pixel, line, lat, lon, height) - Inspect and visualize GCP grid (pixel space + geographic space) - Pixel-to-geographic coordinate transformation via GDAL GCP transformer - Warp SAR data to WGS 84 using gdal.Warp() with GCP-based reprojection - GCPs on SLC burst subdatasets (BURST open option) - Command line usage examples Aligned to repo template: YAML front-matter, EOPF logo, ToC with MyST anchors, Overview hint block. Closes #229
