Pull request overview
Adds a generalized image/mask flipping utility to help normalize ITK images into an identity (VTK-friendly) orientation before downstream processing.
Changes:
- Replaces the prior identity-direction flip method with a more configurable
flip_image(...)API (per-axis flips + optional identity-direction reset). - Adds support for flipping an optional mask in lockstep with the image.
- Optionally resets the output direction matrix to identity after flipping (intended for ITK↔VTK interoperability).

ITK images have orientation information, but VTK images do not. So, when images are passed to VTK and VTK returns objects (polydata), that polydata will have been created from the image without consideration of the image's orientation, so the polydata will not align with the original (oriented) image.
This function allows an image to be flipped into a neutral (identity) orientation before passing to VTK.
