PDS Compressed Images

Description

Here is Ludovic's patch which should fix the PDS "compress"/"uncompress" sections.

Now the compessed section should only be a jpeg2000. Would it be easy to allow gdal to open the Jpeg2000 using the parameters from the PDS label? That may mean even if the Jpeg2000 image has a geospatial header - hmmm.

A small test image would be: http://imbrium.mit.edu/DATA/LOLA_GDR/CYLINDRICAL/IMG/LDEM_4.LBL http://imbrium.mit.edu/DATA/LOLA_GDR/CYLINDRICAL/IMG/LDEM_4.IMG low-res lunar DEM.

I have applied a variation of the patch in trunk (r21616).

I adjusted the GetKeyword?() a bit so we could avoid the ackward use of CPLString().Printf().

I also skipped the part of the patch that disabled compressed images - I'm not sure what it's rationale was.

I also tried to be more consistent pulling IMAGE. keywords with the prefix even if they didn't seem to be found in the test image.

The patch included a new test suite entry with the referenced sample image (truncated).
