Generate segmentation patches for faster ROI-based segmentation

### Description of feature

SOPA implements patching to get focused segmentations. This needs to be implemented in spatialxe to have ROI-specific segmentation. This also would speed up cellpose/basyor/proseg steps and reduce the overall GPU vram usage
