WCS-T doesn't support CInt16

[Dimitar Misev]

While importing Sentinel 1 SLC data with wcst_import.sh:

Attached is a sample tiff file.

Rasdaman supports only 64 and 128 bit complex numbers (floating point only). We should extend this, best to match the GDAL complex number types: ​http://www.gdal.org/gdal_8h.html#a22e22ce0a55036a96f652765793fb7a4

We could map that to r_Complex, but the problem is that r_Complex is 64 bit (which is the smallest complex type rasdaman supports).

Gdal supports from 16 to 64 bit complex types: ​http://www.gdal.org/gdal_8h.html#a22e22ce0a55036a96f652765793fb7a4

I guess it's time to add more complex types in rasdaman?

a valid request indeed - Sentinel is important. Hope we can find resources - maybe someone from the community would like embark on this…
