Nikon .nd2 fixes, part 3

Fixes the following:

 * https://trac.openmicroscopy.org.uk/ome/ticket/11305 (QA 7534, 7535, and 7536)
 * https://trac.openmicroscopy.org.uk/ome/ticket/12205 (QA 9183)
 * https://trac.openmicroscopy.org.uk/ome/ticket/10773 (QA 5042 and 7303, data_repo/from_skyking/nd2/sara/, and data_repo/from_skyking/nd2/richard/Nf1#49-#54.nd2)

That represents the last batch of .nd2 bug tickets for 5.0.3.

As with previous .nd2 PRs, importing the relevant files into OMERO or opening in ImageJ is sufficient - there should be no error messages, and no obvious problems with the images (e.g. mixed up channels/timepoints/positions).  Most files can also be verified with http://www.nikoninstruments.com/Products/Software/NIS-Elements-Viewer/.  Note that the two ```data_repo``` files mentioned above are quite large, and so may be difficult to test in Nikon's software (and if you open them in ImageJ, the ```Use virtual stack``` option will be necessary).
