Bump imglib2 version to 2.0.1

Unfortunately, while the 2.0.0 release included everything we wanted,
it did not _remove_ everything we meant to remove.

The 2.0.1 release exists to remove all of those things:

* net.imglib2.AnnotatedSpace and net.imglib2.Axis
* net.imglib2.multithreading
* net.imglib2.roi and net.imglib2.labeling
* All deprecated methods and classes
