Add ability to view Materialized Views

[datasci-iopsy]

This VS Code extension is fantastic. One thing I noticed recently is that I am unable to see materialized views that live in my BigQuery environment. I can see Routines, Views, and Tables seamlessly; however, any materialize view that I create in my environment does not show. Is this a feature that you can add? Please let me know if you need additional information or if you are actually able to see materialized views already.

I'll take a look at this next time I get around to updating the extension!
