Refactor/rest op

[dskiba]

Motivation

1. Better performance. No needs to do 2 interactions over arr (filter, reduce)
2. Add typings for restOp (using Omit version https://stackoverflow.com/a/53968837/12853087)
3. Add tests for restOp

Summary

Improved performance, by reducing interactions (ON)
Add typing for restOp (see TS playground)

Added test for it

Test plan

it('can get rest keys from object', () => {
  const obj = { one: 1, two: 2, three: 3 };
  const rest = restOp(obj, ['two']);
  // eslint-disable-next-line no-unused-vars
  const { two, ...expectedRest } = obj;
  expect(rest).toEqual(expectedRest);
});

added works well, but pre-commit hooks failed

 FAIL  __tests__/detect-core-js.test.js
  ● Ensures that package do not include core-js dependency after build

    expect(received).not.toContain(expected) // indexOf

    Expected substring: not "The corejs3 polyfill added the following polyfills"
    Received string:        "@babel/preset-env: `DEBUG` option
    
    Using targets:
    {
      \"android\": \"90\",
...

As I see some tests failed, If you know how to fix them, let me know, please. Since I did not touch that files or tests.

Hi @dskiba!
detect-core-js fails because your changes introduce some syntax that requires core-js. In that specific case, you use includes:

    The corejs3 polyfill added the following polyfills:
      es.array.includes { \"android\":\"90\", \"chrome\":\"90\", \"edge\":\"90\", \"firefox\":\"88\", \"ie\":\"11\", \"ios\":\"14\", \"opera\":\"75\", \"safari\":\"14\", \"samsung\":\"13\" }
      es.string.includes { \"android\":\"90\", \"chrome\":\"90\", \"edge\":\"90\", \"firefox\":\"88\", \"ie\":\"11\", \"ios\":\"14\", \"opera\":\"75\", \"safari\":\"14\", \"samsung\":\"13\" }

Oh, okay thank you. I'll change it to the 'indexOf' method
