If you're on Linux, then you could write the buffer in a /vsimem/ file
(gdal.FileFromMemBuffer('/vsimem/foo.nc', blob) ), and use the netCDF driver
on that file.
Actually we could likely remove the Linux-only restriction for the particular
case of /vsimem/ files but this isn't implemented currently in the driver.
