[v7] Column toggle visibility feature

To add column show/hide functionality(via user actions), there seems to be following ways :-

1. Add a new hook, which have default state, detach current show attribute from columns and derive it from plugin’s default state and add needed column methods.

2. Keep the current data structure, add a new method to column for toggling visibility, but will require one more property apart from isVisible and show.

3. Manage the state outside of react-table, by updating the columns config itself.

@tannerlinsley , what are your thoughts on it and what would you prefer ?

Can you think of any reason why a dev would want the show option and not just want to use a hypothetical column visibility plugin?

For features like providing toggling functionality at user level, something like given in snapshot on this link https://github.com/tannerlinsley/react-table/issues/1649#issue-525806262
