Dictionnary renderer: add support for $view in `dictionnary_script`

NicolasGIS

Hello,

Dictionnary renderer is very powerful and I love it !

But having implemented few dictionnaries, I really miss the `$view` from the Arcade profile to configure the rendering style according to the scale in the `dictionnary_script`:

Thanks for listening !
