Drivers don't appear out of spontaneous generation -;)

There are interesting resources online:
* introduction
https://earth.esa.int/web/sentinel/sentinel-1-sar-wiki/-/wiki/Sentinel%20One/Level+1+Product+Formatting
* format specification
https://earth.esa.int/c/document_library/get_file?folderId=349449&name=DLFE-4503.pdf
* test data
https://earth.esa.int/web/sentinel/sentinel-1-sar-wiki/-/wiki/Sentinel%20One/Test+Data

I've downloaded a few test datasets and you can already read the GeoTIFF files in them.
Depending on the nature of the product, they might be of complex data type (CInt16) or not.
They have GCPs, so you need to use gdalwarp to rectify them.

There's a huge quantity of metadata in the companion XML files.
A potential driver should likely select the ones that are the most interesting to report. A bit like
DIMAP 2.
