Error handling - what if one or more advisories didn't return? #3

[jossef]

copied from #3:

Today we have three states for the indicator: Loading, Good, and Bad.

What should we display if one of the advisories returns an error (for example, the API is broken)?
What if all except one return an error?
What if all?

Is it a Good state (because there are no bad scores)? Is it Bad?

Sometimes, the command doesn't contain a real package name, but just an example name like npm install @my/scoped-package.

In this case, we need to understand from the advisory if it doesn't return because the package doesn't exist, and pass this information to the UI.
