Feature request - allow '==' equality with an option about deep-eql HOT 2 OPEN

I was able to do it using the undocumented options.comparator, like this:

function isPrimitive(value) {
    return value === null || typeof value !== 'object';
}

function loose(a, b) {
    return isPrimitive(a) && isPrimitive(b) ? a == b : null;
}

Seems to work - for example:

console.log(deepEqual(3, '3', { comparator: loose })); // true

console.log(deepEqual({foo:3}, {foo:'3'}, { comparator: loose })); // true

console.log(deepEqual([3], ['3'], { comparator: loose })); // true

The isPrimitive function is already present internally in the library, so adding this feature should be very simple - the main question is what would you expect the API to look like, how would this work with other comparators, etc.?

I guess the most generic way to add this would be to expose the comparison function in the options.

In other words, documenting it seems enough for my use case.
