[FEA] DeepZoomGenerator

[Pidem]

Is your feature request related to a problem? Please describe.
I would like to generate tiles for pathology images and need cuCIM to support the openslide.deepzoom.DeepZoomGenerator class

Describe the solution you'd like
support the DeepZoomGenerator that wraps CuImage

Describe alternatives you've considered
Using Open-slide only and not cuCIM

Additional context
Urgent request for Foundational Model training

Hi @Pidem ,

Thank you for the feature request!
Would you mind sharing more details about your use case?
Do you require the exact same API as OpenSlide's DeepZoomGenerator API (link) for visualization as well, or do you primarily need to generate tiles at a specific zoom level (for levels not supported by the underlying TIFF's tile levels), tile size, or overlap specifically for training purposes?

I'm also curious to know which part of the existing API makes it difficult to adapt to your needs.

Please also let us know if using tiffslide (based on tifffile) would suit your use case. We'd love to hear more about your specific requirements (e.g., performance, usability) for your use cases.

Thanks!

I am generating the tiles at a specific zoom level and generating an embedding representation of a given slide using a vision foundational model. I am not exactly sure how tiffslide and cucim differ from each other
