feat: adapt to voila-sepal-ui template. #909

This is related to #909.
There are only few changes that I had to do. As I reported in widgetti/ipyvuetify#308, VuetifyTemplates don't have a metadata_id and is not possible to identify them on a straighforward way, that's why I added a class tag to the main scripts we are using "copy to clipboard" and "fullscreen" for maps, in this way they will be displayed in the DOM when using display method.
I didn't set this tag to the other styles and js's we have here because they are obsolete within the new template.

Actually, I simplified the full screen event by just adding/removing a css class, that will make the trick work and we'll use less code.

@12rambau, I came up with a simpler solution for the full screen that doesn't require to use the vuetify template, and works well in both scenarios.

I let you decide if you want to accept my suggestion but for the rest it's good to go !
