Feat: nicer CLI output

[lirantal]

Currently, the CLI outputs the following results for a scan:

❯ npx snync --directory . --private "superlaser"
npx: installed 68 in 6.711s
Testing project at: /Users/lirantal/projects/repos/dependency-confusion-demo/packages/new-project

Reviewing your dependencies...

Checking dependency: some-new-package-that-is-not-on-npm
  ->  ⚠️ vulnerable
Checking dependency: superlaser
  ->  ❌ suspicious

It's nice, but could probably have better-styled output. Happy to receive ideas and suggestions which we can mock around quickly once we agree on one we can land a PR for it too.
