[proposal] SD-jwt integration

**Is your feature request related to a problem? Please describe.**
The SD-JWT is used in the ARF and gets a lot of attention by EU projects. Main key points are the capability of selective disclosure AND being built on the widely adopted format JWT.

**Describe the solution you'd like**
We should be able to use some of the existing libraries to create sd-jwts and create a wrapper to use them in Veramo.

**Describe alternatives you've considered**
Right now I see no other approach using selective disclosure with Veramo (maybe with micro credentials where each credential only includes one value)

**Additional context**
We need to challenge how the existing selective disclosure approach can be used or even becomes a problem when integrating sd-jwts.
