Julia: chunkread: Expose option for reconstructing image data arrays/detgeom

It makes a big performance difference to avoid creating these arrays.
We will just need to deal with the fact that an Image might not have a
DetGeom or data arrays.

This commit also sets sensible chunkread options for allcrystals().
