BUG: Fix slicing. More consistent with numpy #721

Closed cookpa closed 1 month ago

cookpa commented 1 month ago

Fixing slicing issues detailed in #719. The behavior of slicing should now be consistent with what you get on a numpy array, except that it returns an antsImage for slices with dimensions >= 2.

When slicing by indices, direction matrices are collapsed to identity. Users need to call the slice_image function to control that.

I added support for negative indices, so you can do something like im[:,:,0:-1] and it behaves as numpy does.
