Compliance Presentation Exchange v2.x.x

[n0900]

Need to update our references from presentation exchange 1.0.0 to 2.0.0 or later.
Also necessitates potentially updating relevant classes.
Notably InputDescriptor does no longer contain member schema

still relevant @n0900 ?

[n0900]

Yes, changed the mentioned InputDescriptor but have not touched any other part of the spec
