RectangleNeighborhoodCursor.jumpFwd(1) results in incorrect position. #6

Hi @tpietzsch !

I believe I found a bug in RectangleNeighborhoodCursor:

On a fresh shape.neighborhoodsSafe(img).localizingCursor() fwd() results in position [0, 0, 0], but jumpFwd(1) results in position [2, 0, 0].

I wrote a simple test for this: here

When letting the cursor run through the entire img with .jumpFwd(1), an ArrayIndexOutOfBoundsException is thrown.

Greetings, Squareys

Does this work as expected?
