Rename OME-XML tool command
Move OMEMetadata to io.scif.ome package
Move OME formats to io.scif.ome.formats package
Move OME translators to io.scif.ome.translators
OMEXMLService: simplify javadoc

This service will become a wrapper around the Bio-Formats (non-SciJava)
service of the same name, so let's just reference those other javadocs.
OMEXMLFormat: eliminate dep check via reflection

We don't do soft dep checks for any of our other dependencies,
so let's not for OME libraries either.

If we wanted to make the OME dependencies optional, they should be:
A) flagged as such in the POM; and
B) we should catch ClassNotFoundException rather than checking via
   reflection using the default class loader.
Use a compatible version of SLF4J
Simplify OMEXMLService

Let's just delegate all the methods to
loci.formats.services.OMEXMLService instead of forking the code.
Rename OMEXMLServiceImpl to DefaultOMEXMLService

This naming scheme is consistent with all other SciJava-based services.
Move services packages to io.scif.ome.services
DefaultOMEXMLMetadataService: tweak javadoc
OMEXMLToolCommand: fix javadoc links
OMETIFFFormat: add FIXME reminder
OMEXMLFormat: fix resource leak warning
DefaultOMEXMLMetadataService: use MetadataTools

Some of the methods provided by the OMEXMLMetadataService are simply
wrappers around tools of loci.formats.MetadataTools. Let's lean on that
static utility class where applicable to avoid copy/pasting any code.
OMEXMLMetadataService: simplify javadoc

The old version looked to be a copy/paste from Bio-Formats,
and portions of it was no longer relevant.
Rename OMEXMLMetadataService to OMEMetadataService

The new name is more concise, and less easily confused with the
OMEXMLMetadataService.
DefaultOMEMetadataService: depend on OMEXMLService

This provides a stronger guarantee than grabbing the OMEXMLService
later out of the application context.
POM: fix copyright to be more accurate

SCIFIO-OME-XML is a new project developed at LOCI. Glencoe Software
and the University of Dundee are not actively developing this component.
That may change in the future, but for now, LOCI has the sole copyright.
Upgrade Bio-Formats dependency to 5.0.0
