utils.deflate()

We can deflate objects with _spy.utils.deflate().

_spy.utils.deflate({
  a: {
    b: 1,
  },
  c: [2, 3],
  d: {
    e: [
      { f: 4 },
      { g: 5 },
    ],
  },
});
/*
{
  "a.b": 1,
  "c": [2, 3],
  "c[0]": 2,
  "c[1]": 3,
  "d.e": [{"f": 4}, {"g": 5}],
  "d.e[0].f": 4,
  "d.e[1].g": 5,
}
