[FEA] Provide a way/example to use cuCIM with Dask for DataLoading(Pytorch's Dataloader-like API) about cucim

I would be happy to take a look at this!

NVTabular's pytorch dataloader (which is built on Dask) may be agood reference here. I'll be happy to help advise on this work and clarify what NVTabular is (and isn't) doing.

Thank you, @rjzamora !

Unfortunately, I have come across some issues with the cuCIM codebase that are blocking this Dask-based DataLoading solution.

For example, while the array transformation in the cuCIM transform image_rotate_90() should be compatible with a Dask Array input, there is an explicit Type-Check here that throws a TypeError whenever trying to apply cuCIM transforms to a Dask Array.

In order to allow Dask to schedule cuCIM operations - we will likely want to make this "check" more of a duck-type check, that checks for the necessary API interface, as Dask Arrays should be able to pass those checks.
