Consolidated services to ome.scifio.services

When many of these services were first implemented, it was not clear
what role the ome.scifio.services package would serve as it still housed
an unconverted ServiceFactory API.

Now that the ServiceFactory API has been converted to a scijava-common
service architecture, it makes sense that all SCIFIO scijava-common
services be located in the ome.scifio.services package.
