Introduce reversible padding support and transform metadata for Image/Mask Autosize.
- Add a new 'pad' crop_mode that preserves aspect ratio with reversible padding.
- Introduce AutosizeTransform dataclass and AUTOSIZE_TRANSFORM IO type.
- Add helper functions (_to_samples, _from_samples, _apply_transform, _resize_samples) and use them in ImageAutosize.
- Add two nodes: ImageAutosizeApplyTransform and ImageAutosizeRestore to apply transforms to aligned masks and restore original dimensions.
- Update tests, README, and CHANGELOG and bump package version to 0.3.0.
