[Feature] Option to use double quotes for strings

[ajboni]

It would be really nice to have an option to use double quotes instead of single quotes for strings.

test("quotes", () => {
  const obj = toml.parse('title = "test"', { joiner: "\n" });
  const out = toml.stringify(obj, { newline: "\n", T: " " });
  expect(out).toEqual('title = "test"');
});

- title = "test"
+ title = 'test'

@ajboni Now v1.25.0 is released, toml.parse('title = "test"', { joiner: "\n", x: { literal: true } }) / toml.basic may help. Welcome to foretaste, and give any feedback.
