feat(composable): add a new composable

[jy0529]

add a new compoasble useTimeout, #506

LGTM

My only nit pick are the tests, because of awaiting for a timer to run off, there's a change it won't be executed property.

Thank you,

wow, thanks, I will learn more about jest, and I refactor this tests, do you think this well?

`describe("timeout", () => {
beforeAll(() => {
jest.useFakeTimers();
});

afterEach(() => {
jest.clearAllTimers();
});

afterAll(() => {
jest.useRealTimers();
});

it("should be defined", () => {
expect(useTimeout).toBeDefined();
});

it("should call passed function after given amount of time", () => {
const callback = jest.fn();

useTimeout(callback, 1000);

expect(callback).not.toBeCalled();

jest.advanceTimersByTime(1000);
expect(callback).toBeCalled();
expect(callback).toHaveBeenCalledTimes(1);

});
......more tests
}
