This commit will optionally continue past images that Kakadu won't convert, if the --ignore-broken-images option is provided.
With respect to the errors this PR directly addresses, in both cases the images would not open in GIMP, nor do they show in BookReader. They seem to be corrupt and I cannot figure out how to salvage them.
