Add modulo support for LI-FLIM data (rebased onto dev_5_0)



This is the same as gh-1164 but rebased onto dev_5_0.

----

Fixes http://trac.openmicroscopy.org.uk/ome/ticket/12290.  Phase and frequency dimensions in LI-FLIM files are now stored in the appropriate Modulo annotation, rather than being stored as separate series/Images.

To test, verify that QA 9236 has two Images when imported - the first should contain 12 planes (for 12 phases), and the second should contain a single plane (the background image).

I would suggest also checking other datasets from the ```data_repo/from_skyking/li-flim``` directory, as many of those files are also multi-phase/multi-frequency datasets which have now had their import behavior changed.  In all cases, I would expect no more than 2 Images to appear after import.
