numbered results for test and io.test.all output

[ceedubs]

Is your feature request related to a problem? Please describe.

When a test fails, I often want to look at the source code for the test.

Describe the solution you'd like

Right now the output of the test command looks like:

   ◉ time.patterns.asctimeFormat.test        Passed
   ◉ time.patterns.rfc7231DateTime.test850   Passed
   ◉ time.patterns.rfc7231DateTime.testIMF   Passed
   
   ✅ 3 test(s) passing

It would be nice if the output looked like:

   1. ◉ time.patterns.asctimeFormat.test        Passed
   2. ◉ time.patterns.rfc7231DateTime.test850   Passed
   3. ◉ time.patterns.rfc7231DateTime.testIMF   Passed
   
   ✅ 3 test(s) passing

And I could do view 2 to view time.patterns.rfc7231DateTime.test850.

Describe alternatives you've considered

N/A

Additional context

I think that this applies to both test and io.test.all.

The test output can be a bit more complicated than what I've pasted above. There can be one section for cached results and another section for new results. Also there can be failing tests.
