Impact: Bug fix. ### Description: Fixes #3264. Import PIL Image for the existing bytes and bytearray decode path in the MMSeg transform. Array-backed inputs are unchanged. Validation: git diff --check passed. No tests or builds were run per assignment. ### Things to be aware of: The fix is scoped to the reported call path and preserves the existing API. ### Things to worry about: Tests and runtime validation were not run. ### Additional Context: No additional dependency or migration changes.

Walkthrough

The MMSeg transform module now imports Image from PIL. The transform uses Image.open when handling byte-backed images.

Changes

MMSeg image handling

Layer / File(s)	Summary
Image import python/deeplake/integrations/mmseg/compose_transform_.py	Adds the PIL Image import used by the transform. This resolves the undefined name in the byte-backed image path.

_{A rabbit finds an image byte,
The missing name now comes to light.
PIL joins the transform’s way,
Byte-backed pictures pass its gate,
And hops resume through pipeline straight.}
