OrthancSeriesProgressiveLoader now has two modes that
can be selected at object creation :
- progressive (will first load jpeg50, then jpeg90 then PAM)
- non-progressive (will directly load PAM (uncompressed))
Please note that the slice loading order remains dynamic
and depending upon the slice that the client code wishes
to extract from the volume.
