[Ubuntu] ZSTD Support GDAL 2.4/2.4.2

[Zhen Wang]

Hi all,

Using gdal ubuntugis-stable and ubuntugis-unstable, but both seems to not
have ZSTD compression enabled ?

I get the following output:

gdal_translate -co "COMPRESS=ZSTD"  test_gdal test_gdal_translate
Input file size is 100, 100
Warning 6: 'ZSTD' is an unexpected value for COMPRESS creation option of
type string-select.
0Warning 5: COMPRESS=ZSTD value not recognised, ignoring.
...10...20...30...40...50...60...70...80...90...100 - done.

gdal_translate -co "COMPRESS=LZMA"  test_gdal test_gdal_translate
Input file size is 100, 100
0...10...20...30...40...50...60...70...80...90...100 - done.

I get similar results with rasterio.open() using ZSTD as compression

Cheers,
Zhen
