Launch extension: allow `eventInfo` to be retrieved with data elements

[yuhui]

Expected Behaviour

Given an ACDL push like so:

window.adobeDataLayer.push({
  "event": myEvent",
  "eventInfo": { foo: "bar" }
});

Then there should be an ACDL data element type that when provided with the key eventInfo.foo, the data element returns "bar".

The Data Layer Computed State data element type is not able to read eventInfo, because eventInfo does not persist in the data layer.

Actual Behaviour

There is no such data element to retrieve eventInfo fields.

Steps to Reproduce

See "Expected Behaviour".

Platform and Version

All platforms, all versions.

Sample Code that illustrates the problem

See "Expected Behaviour".

I mentioned this to Benedikt Wedenik as well, so thumbs up for it. Though this is only the ACDL itself and not the Launch extension built around it. Not sure if there is now a separate github space for it.

In case it helps, I believe you can create a Custom Code data element with the following:

return event.eventInfo.foo;
