Persist radar choices

So admittedly I don't really feel so good about this implementation.

I feel confident about the way I store the session data into local storage, but the way I retrieve session storage and how I add it into the store... I feel less comfortable with.

Also, this has a known issue in that restoring from local storage will definitely update the graph but it won't update the sliders on the right, and that's because it seems to be a bit of a known issue with react-likert-scale (see here)

OK I'm much more comfortable with the solution I have now - it uses modern React effects to manage the rendering once in our functional component without much additional code.

There was a eslint warning which I intentionally disabled in SkillsSelector.js as what I'm doing is very intentionally doing the equivalent of componentDidMount and not componentDidUpdate, which needs dependencies in the array (on line 19).
