Revert "Move from loci-legacy to scifio dep for OMEXMLService"

This reverts commit 19a350d2a05a3d76aeb8e64d4cde9d1457905646.

Not possible to have specification depend on SCIFIO since that
introduces a circular dependency. What that means is that spec/
can't use OMEXMLService (or the home of OMEXMLService must move)
Move spec tests needing transforms to scifio
TMP: try
Copy {transforms,released-schema} to target/classes

This would be MUCH easier if these directories were
under src/ or resources/ or any other directory.
