Customizable VC displays

[pmigueld]

Is your feature request related to a problem? Please describe.
VC details are currently hard-coded into one single design and must be customizable to adapt to various ID designs.

Describe the solution you'd like
One possible solution is to have a selection of display components in React Native that will be specifically tied to one ID design. The consumer can select which design to use through the VC schema or some other variable to change how it shows in the app.

TODOs

• Add new folder for the VC components components/vc-displays/...
• Create a fallback/default simple display which will just iterate through the keys in the credential subject and list the data linearly (could also be useful for debugging)
• Create sample VC display component
• Add documentation in the wiki on how to create a custom VC display
• (optional) Create sample VC ID display component (perhaps using the ID PASS editor?)
