Align dev environment with ClearWater-Riverine

[aufdenkampe]

It makes sense to work toward similar if not identical development environments for both ClearWater-Riverine and ClearWater-modules-python. This will help with this next phase of integration, even though it will be less important once we properly package each library.

Thanks for the suggestion @jrutyna!
