[gdal-dev] VRT File Support Within a Zstd-Compressed Zip

[Jordan Dauble]

Good afternoon, I would like to request that a new feature be added to GDAL. Our team has found that while both libzip and GDAL support Zstd compression, the support does not extend to loading vrt files within a Zstd-compressed zip. We have a use case where the vsizip file handler is used on a Zstd-compressed zip, such as
ogr2ogr outputTest.gpkg /vsizip/{<zip_filename>}/extent.geojson.

We believe the following files would require modification to support this feature:
port/cpl_minizip_unzip.cpp
port/cpl_vsil_gzip.cpp
