Add dependencies check in rvw & use-case

Add check to reviewer checklist: Dependencies are documented and appropriate

Also address this comment: "“I'd also include the goal or 'use-case' of the software (not necessarily the scientific purpose). Is this release intended for others to 'grab' and use this scientific software in new use cases? Or is this just an 'archive' of something that worked once, to support a paper. I'd approach both of these very differently as a reviewer, in terms of the requirements I'd want to see (and maybe even have the checklist be different)” "
