Add support for displayObjectSize

[axelniklasson]

Hi! Thanks for working on this, this is a great alternative to https://github.com/mac-s-g/react-json-view 👍

I was wondering if there are any plans to add support for the displayObjectSize prop that is available in the other library? I'd love to use this library in our product but I want to hide the size label for all objects in the JSON field, which would be done through setting displayObjectSize: false in the the old project.

I'm thinking of adding props.features.displayObjectSize because we would support much customizable stuff in the future.
