Support Orion profiles

[apexskier]

https://orionbrowser.com supports multiple profiles, each of which is run as a separate instance of the Orion binary. Only one "Orion" shows up in the default browser UI, and only the "main" profile is opened, even if another profile was last used.

I did some digging today on this:

Each profile appears as an individual bundle in ~/Applications/Orion/Orion\ Profiles/{uuid}/Orion\ -\ {profile}.app. These aren't standard, swift's Bundle type can't load them, and CFBundle can't read the info dictionary. (I can load them directly through conventional file reading, but the app sandbox prevents this without some workarounds).

The bigger issue is that the App Change Notification always shows the main Orion app (the bundle ID, url, and executable URL are all Orion.app, not the profile) so I don't think I can actually know which profile was used.

#44 helped this. The app now can discover profiles and show them in its list. Unfortunately, however, this doesn't help the App Change Notification issue.
