compound Name is lost when writing out file

[aghariani]

The name of the Compound coordinate system is changed to unknown when saved.

Example:

gdalwarp -t_srs EPSG:32636+3855 input.tif output.tif

gdalinfo on the resulting file is giving:

COMPD_CS["unknown",

PROJCS["WGS 84 / UTM zone 36N",

GEOGCS["WGS 84",

DATUM["WGS_1984"......

Same thing with the c++ api when setting the projection as a COMPD_CS with a name, the COMPD name is lost on writing out the file.

GTiff: when reading a COMPD_CS (and GTIFF_REPORT_COMPD_CS=YES), set the name from the GTCitationGeoKey (fixes #7011)
