Title: Better information when requirements aren't met

This PR improves enpkg's error messages to users in the case where some requirement is not met, either because of a non-existent package, or a package which the user doesn't have access to.

This PR tries to show which packages are likely to be alternatives, and gives the user a pointer to how they might be able to be installed.
