As described here
https://developer.android.com/training/app-links
We are using the result of this PR https://github.com/joreilly/Confetti/pull/1215/files to support autoVerify and have the app automatically pick up these links.

Keeping it as a draft until I get some feedback on this. Until then the implementation itself can be reviewed if there's anything else that we need to do here. I hooked the initial id to the AppComponent which takes over instead of looking at the local preferences and if there was some conference selected in the past. At the same time it also saves this conference to storage.

The one other thing which this does not handle well is the color scheme of the conference itself. I believe there's room for the color to be implicitly linked with a conference ID so that a deep link can just pick it up from there, instead of having to know the color as you are setting the selected conference. Maybe something to consider as a PR on top of this, depends on what you think about it too.

p.s If deep links exist, someone could definitely try to deep link to /asd123a for example. It may be a good idea to also possibly show a special error message in those scenarios when the backend successfully responds with no conference information. Or we might have to tweak backend to respond in a special way, with a special error in the response for example for those cases.
