Update to scifio-itk-bridge 1.2.0

1.2.0 fixes a bug where Bio-Formtas 5.0.4's logging prevented operation
of the Java : C++ pipe.

It also adds hand-shaking after each plane and image is written, which
required updates to the C++ side as well (as hand-shaking is now
bi-directional, instead of just Java > C++). This fixes a race condition
when writing planes.
