feat: disable jsx per story

[petermikitsh]

Closes #109

This adds the functionality to disable via CSF:

export const Simple = () => (
  <div>Hello</div>
);

Simple.story = {
  parameters: {
    jsx: {
      disable: true,
    },
  },
};

I tried to add an example to the example directory, but I'm struggling since these stories don't use CSF format

So the change is basically wrapping the decorator in makeDecorator?

It's fine there is no example. Could you add an example to the README.md?

Correct. makeDecorator contains the logic to short-circuit the addon when it is disabled.

Also, I've updated the README
