GCPs in tiff files only provide ('longitude', 'latitude', 'height'). In the xml file, some variables are also provided, like 'azimuth_time', 'slant_range_time', 'incidence', and 'elevation'.
PR #38 from @agrouaze has done most of the work to read those variables from xml file, but to reduce the PR size, we can do a specific PR on this item.
The new structure can be called s1meta.geoloc, but after some validation, it will replace s1meta.gcps, as s1meta.gcps is a subset of s1meta.geoloc.
geoloc might be added as a compound_var in sentinel1_xml_mappings.
