new(responsive): add ignoreDimensions prop to handle rerenders

[wyze]

🚀 Enhancements

This PR

• add a new prop to ParentSize (disableFor) to skip when a component doesn't want to be notified by a size change of a certain prop
• also converted the class component to a functional component (hopefully was ok). I did that in a separate commit so you could see what was needed for the feature

Note: I did attempt a test and was unsuccessful, so more than happy to add one provided some direction. I use react-testing-library, so unsure how to simulate resize of an element with enzyme.

Also, disableFor might not be the best name for the prop, so I am open to changing it.

Thanks for the addition @wyze, and the FunctionComponent refactor! 💯

I had a couple of small suggestions but otherwise lgtm. I think for now don't worry about new tests, mocking these things in enzyme isn't super easy / I can add the boilerplate later.
