CoreMetadata: update copying constructors to initialize Modulo values
Allow one Modulo annotation of each type for every Image

Previously, only one ModuloZ, ModuloC, and ModuloT was allowed across
the board, which meant that multi-Image datasets could not use a
different Modulo definition for each Image.
Flex: be more permissive in parsing IFDs and XML

This allows a trailing ">" in the XML block, in addition to forcing more
thorough IFD parsing when the images are stored before the IFDs.

Cellomics: a few fixes for single-file datasets

This allows the field to contain either 2 or 3 digits, and fixes the
image name setting so that field/well indices are not 0.
Cellomics: fix reading of directories with mixed o/d channels

The channel letter for the initial file is respected now, instead of
allowing any file with a matching name.
One more fix for channel file grouping
