fix: updated factorpaths
Renamed scifio Core Metadata classes

ome.scifio.CoreMetadata is now ome.scifio.DatasetMetadata
ome.scifio.CoreImageMetadata is now simply ome.scifio.ImageMetadata

This renaming was done to explicitly match the OME model of datasets as
collections of images.

All references were updated
Removed Translator from Writer#setMetadata

The setMetadata methods were requiring a Translator parameter to
generate CoreMetadata.

This is now handled in the AbstractWriter layer via automatic detection
through the Format.
SCIFIO package documentation

Added package-level documentation, via package-info.java classes, to the
scifio-devel component.

The goal of this documentation is to concisely convey:
* current functionality of the SCIFIO classes
* rationale for significant changes from Bio-Formats
* intended future changes
Removed redundant package.html

The ome.scifio.common and ome.xml.meta package.html files were not
necessary, as there is now a package-info.java for describing these
packages.
Updated Javadoc components

Added the scifio-devel and loci-legacy projects to the list of javadoc
sources.

Also added the imglib2 and sezpoz jars to the javadoc classpath.

Removed loci-common project from the javadoc source list, as it is
a sourceless pom project.
