Allow installation with CuPy 10

[grlee77]

Now that CuPy 10.0 is out, we should also allow cuCIM to be installed with CuPy 10.x in the next release.

I checked the integration repo and it has the same constraint proposed here

[grlee77]

okay, I guess /conda/recipes/cucim/meta.yaml had already been updated in #195, so this is now just an update of conda/environments/env.yml

Perhaps we should just drop this constraint? I think the original motivation was to ensure we got CuPy 9 as we needed the very latest features. Do things work without a constraint here?

Edit: Alternatively we could just keep the lower bound. Since the goal of this is for use in development, we may need to use versions that have not yet been confirmed to work with cuCIM or the rest of RAPIDS. So having some flexibility helps.

I am fine with just keeping the lower bound. I think it should tend to find 10.0 without the constraint, but it doesn't hurt to indicate that it is incompatible with 8.x.
