No support for organic_in_app_events

There currently does not appear to be support for pulling in the organic_in_app_events report from appsflyer mentioned [here by appsflyer](https://dev.appsflyer.com/hc/reference/get_app-id-organic-in-app-events-report-v5). This results in the data pulled from appsflyer via stitch being materially incomplete.

Is it possible to add this?
