Algorithms and utilities for Synthetic Aperture Radar (SAR) sensors -- scripts

 Enables cloud-native SAR processing via Xarray and Dask.
 .
 Sarsen is a Python library and command line tool with the following
 functionalities:
 .
   * provides algorithms to terrain-correct satellite SAR data
     - geometric terrain correction (geocoding)
       * fast mode: to terrain-correct images
       * accurate mode: for interferometric processing
     - radiometric terrain correction (gamma flattening)
   * accesses SAR data via xarray-sentinel:
     - supports most Sentinel-1 data products as distributed by ESA:
       * Sentinel-1 Single Look Complex (SLC) SM/IW/EW
       * Sentinel-1 Ground Range Detected (GRD) SM/IW/EW
     - reads uncompressed and compressed SAFE data products on the local
       computer or on a network via fsspec
   * accesses DEM data via rioxarray:
     - reads local and remote data in virtually any raster format via
       rasterio / GDAL
   * supports larger-than-memory and distributed data access and processing
     via Dask
     - efficient geometric terrain-correction for a full GRD
     - efficient radiometric terrain-correction for a full GRD.
