Please add asymmetric matcher expect.closeTo

[julienw]

🚀 Feature Proposal

There is a matcher toBeCloseTo that's super useful to assert floats. But when these floats are inside objects or arrays we can't use it directly. Therefore it would be useful to have an asymmetric matcher so that we can use toEqual with it, eg:

expect(value).toEqual([
{ start: expect.closeTo(5.3), end: expect.closeTo(5.8) }
]);

It makes sense to be included in Jest core because of the existing matcher toBeCloseTo, that would be more consistent.

Thanks!
