Render output in a tree instead of a flat list

[Raynos]

We have a fantastic divider to structure test output in a tree.

It's files.

We could group the list of green ticks by which file the test('...') occur in.

The only problem is I'm not sure how to place file meta information in tap output or when calling faucet from the cli directly.

When faucet is run with a list of files or on a directory this could be made to work, but TAP doesn't have a standard way of differentiating which file a test was declared in.

Are subtests parsed to TAP as something you can use in Faucet? Example with tape:

test('Card component', (t) => {
  t.test('  should show header', (t) => {
    // some assertions
    t.end();
  });
  t.test('  should show age', (t) => {
    // some assertions
    t.end();
  });
  t.test('  should not show age when not available', (t) => {
    // some assertions
    t.end();
  });
  t.end();
});

Having a tree generated based on files would be great too, but this would only work with specific runners. I'm assuming?
