[ENHANCEMENT] Multiple codes support

[samolukadjo]

Is your feature request related to a problem? Please describe. When a document includes multiple qr/other codes on one page only one is detected and extracted above. This is a problem when, for example, a ticket contains a separate code for the ticket and the return ticket.

Describe the solution you'd like The user should be able to select the codes in the page they'd like to show up above it.

Describe alternatives you've considered The app should detect all the codes in a page that it can and show them one after another above the page, preferably in order they appear on the page.

Additional context N/A
