[impovement]: better output for { depth: 0 } option

[everdimension]

Desired behavior:

qs.parse('items[a]=one&items[b]=two', { depth: 0 });
// —> { 'items[a]': 'one', 'items[b]': 'two' }

Current behavior:

qs.parse('items[a]=one&items[b]=two', { depth: 0 });
// –> { items: { '[a]': 'one', '[b]': 'two' } }

It seems to me that the current output is quite useless, but having a one-level-deep can be quite handy, for example, when dealing with form inputs.

Hmm, there's no explicit tests for a depth value of zero.

To be honest, both of those look pretty useless to me; but I agree with you that the former is what I'd expect with a depth of zero. What do you get with depth: 1?

[everdimension]

with { depth: 1 } you get { items: { a: 'one', b: 'two' } } as expected.

Would you accept a PR for depth: 0?

[ljharb]

I think a PR with associated tests would be great.

This should be fixed by #326.
