Add packages as in app excludes

[ueman]

The Flutter event enricher already supports reading used packages and adding those to an event. This information can be used to mark frames as in app excludes.

Please note, that reading packages is an expensive (as in could take a second or two) operation and should therefore not delay the app start.

That would be done only once tho, if reportPackages is enabled, sounds like something that would improve grouping.
Do you experience bad grouping or is it something that just came up in your mind?

I'm currently using the approach of adding the app package name as in app include and addInAppByDefault = false approach, but based on the packages it could probably done without any manual configuration. So it would be a nice enhancement.

A downside of this is when apps are obfuscated (Web is minified), or AOT via https://docs.flutter.dev/deployment/obfuscate
The inApp detection is always setting all the frames to false.
