Add support for credential embedded images

[nanderstabel]

Description

UniMe currently does not support images embedded inside Credentials as they will currently just be displayed as a long string value.

We need to be able to render such embedded images in a nice way.

In a next iteration we can improve the design further by implementing claim-specific display propterties: https://openid.net/specs/openid-4-verifiable-credential-issuance-1_0.html#appendix-A.1.1.2-3.1.2.2.1. (See #350)

Media types to be supported:

• image/jpeg
• image/png
• image/svg
• Any other media types listed here: https://www.iana.org/assignments/media-types/media-types.xhtml#image

Motivation

Better user experience
