Feature request: Add possibility to exclude/omit keys when comparing objects about deep-eql HOT 2 OPEN

Thanks for the issue @karlitos.

With the current API you can pass in a custom comparator function which gets called on every value so that you can filter it out as you see fit. You could write a custom comparator that deletes the keys like your code does, but it can rely on the rest of the of the internals of this library.

I think the comparator provides enough flexibility with the API to allow for the functionality you’re after.

Could you elaborate more on this please ? So basically the custom comparator be a function which will accept the leftHandOperand, rightHandOperand as parameters, performing the

omitKeys.forEach(key => delete a[key]);
omitKeys.forEach(key => delete b[key]);

and returning the value of deepEqual for them ? But how do I pass the custom comparator to the deepEqual from within the custom comparator ?
