Add "Scan from Camera Roll" option directly to Profile Screen

Because it's FASTER than:

To scan and unlock a Snapcode from your Camera Roll…

1. Tap the Profile icon in the top-left to go to your Profile screen ↖️
2. Tap the Settings icon in the top right 
3. Tap ‘Scan from Camera Roll'
4. Select a picture with a Snapcode in it! 

I'm guessing more people probably screen shot Snapcodes vs. seeing them printed in the wild or on a display somewhere. By saving them steps and creating familiarity with the "Scan from Camera Roll"  function, user will be more apt to use the feature.  As a matter of fact, the "Scan from Camera Roll" option should honestly be added somewhere in the actual Camera Roll because you're already there. 

Thanks!
