Data Bindings: add support for Lists, Images, and Artboards

[kevireilly]

There has been a relatively significant expansion of Rive’s Data Bindings functionality to include Lists, Images, and Artboards.
For more information, see their blog post.

• Lists/Images web example
• Artboards web example

Related to #176 and possibly #58

Lists and images are supported in the 7.3.0 release, by this PR #202

Works great, thanks very much. There might be an issue with the default state of view models not being produced when an instance is created. This may or may not be related to autobinding. Attached is the following small modifications to the Lists/Images web example example above:

• Opened assets/scrolllist.rev (scrolllist-default.rev in the attachment)
• On the Data tab > MainVM > Add [10] list item[s]
• Export as scrolllist-web.riv in the web directory (or adjust index.mjs to refer to new filename)
• Statically host the web build and open rive.html
• Expected web result: there are 10 list items
• Actual defold result: there are not 10 list items
