snowplow_web_events_internal_fixed is not used

[davehowell]

I can't see anything referencing the model snowplow_web_events_internal_fixed

I am following the code based on the model flow graph in the README.

The graph explains that snowplow_page_views references it, but I see nothing in the macro

I also see no entry for it in the schema.yml

I realize it is ephemeral but it should still be referenced in order to inline it as a CTE.

Have I missed something? Or can it be removed and the graph updated?
