We should add some more write parameters to be exposed as ImageWriteParam in order to allow them to go down through the Kakadu machinery.
As an instance, it would be great to allow explicit settings of quality layers bit rates as required by some JP2K Encoding profiles like NPJE and EPJE.
Moreover, the actual writer set a hardcoded Profile==2 as SProfile SIZ param in the compressed image. We should allow setting that too.
Also, the Comment Marker reporting the quality layers distortion slopes will be added depending on the value of the system property
However, we should make possible overriding that system property through an additional ImageWriteParam.
