Title: CLIMATE-487 - Improve error message when local dataset load fails

- Explicit RuntimeErrors are not properly handled to alert the user that
the supplied file path is invalid. This helps clarify user
controllable failures.
- Attempt to make the generic error on dataset loading a bit more
descriptive to help users.
