[Feature Request] Support Universal/Deep Linking to Dolphin Games

[ioslife]

For my use case, I would like to support opening games in RetroArch from my app, RA Tracker. If DolphiniOS supported a custom URL scheme such as retroArch://game/{gameID} then I could add an Open in Dolphin button to my Game Info views.

I am sure there are many other front-end developers that would like to have a functionality like this for opening from their potential launchers as well.

Dolphin for Android has the ability - https://github.com/dolphin-emu/dolphin/blob/01a2cf8db9416b90eef3160a800f7b2560a3ae4a/Source/Android/app/src/main/java/org/dolphinemu/dolphinemu/utils/StartupHandler.java#L44

This won't matter for my app until Dolphin mobile gets RetroAchievement support, but once it has that I would really like to be able to add this feature to RA Tracker.
