ImagePlotly Storybook not working with Storybook 6.1.1

[alex-ketch]

In a recent dependencies update the ImagePlotly story stopped working.

After investigating turns out the script tag in the story gets omitted, and so the plot never renders.
The component itself still functions as before outside Storybook context, as well as when the data is passed in as prop on the WebComponent.

Will need to investigate changes in the Storybook and find/make a potential fix.

This was fixed by a PR to Storybook and deployed in #134.
