cuCIM tile source

cuCIM read_region() is a highly optimized routine for reading from TIFF-like whole-slide images including svs. We should incorporate cuCIM as a tile source.

I think the main difficulty here is going to be generalizing the installation of cuCIM. For all of our other tile sources, we build a python wheel to facilitate the process. Doing so for cuCIM is probably much harder as they have different packages based on GPU drivers.

We can discuss this with the NVIDIA team at our next meeting.

It looks like pip install cucim is now sufficient; the cupy cuda extensions appear to be for some of the cucim image manipulation features.
