allow `unpack`ing from a "clean" OME-XML

[erickmartins]

The use case for using unpack as a bulk import/annotation tool is pretty clear; we already have a structure that relates files to object IDs and that can describe annotations, ROIs and model hierarchy. What would we need to implement to be able to effectively use it as such? How would someone generate an XML from a set of files, potentially edit this XML to add annotations/ROIs/hierarchy, and then just point to the folder containing files + XML for a full unpack?
