Update pom-scijava to 1.70

Updated pom-scijava, which includes version updates and bug fixes to
scijava-common, imglib, and scifio.

Updated TypeService dependencies to SCIFIOService, as TypedService was
removed in the latest SCIFIO.
OMEXMLMetadataService: fix calibration axis types

Was mistakenly reading the X calibration value for all calibration
types.

Fixed to use the correct axis types.
OMEXMLMetadataService: set physical sizes

The physicalPixelSizes of destination MetadataStores weren't actually
being populated using the source calibration values.

They are now properly set. Also updated the OMEXMLTest to include the
calibration values in XML.
Create CalibrationTest class

Added a CalibrationTest junit test. This should verify calibration
values are properly persisted when translating from Metadata to
OMEMetadata.
Merge branch 'fix-calibration'

Update the pom-scijava version to 1.70 to take advantage of CalibratedAxis
fixes in imglib2 and SCIFIO.

Also properly propagates calibration data between OME-XML and calibrated axes
now.

NB: all Services in this software are now SCIFIOServices instead of
TypedServices, as the interface changed in the 0.6.0 release. This does allow
all scifio-bf-compat services to be automatically loaded when a Context is
created using SCIFIOService.class.
