SD-JWT VC implementation

Hi I was just wondering what is the current status of this work :)

Currently when using this branch like this:


[dependencies]
identity_credential = { git = "https://github.com/iotaledger/identity.rs", branch = "feat/sd-jwt-vc", default-features = false, features = [
    "validator",
    "credential",
    "presentation",
    "domain-linkage",
    "sd-jwt-vc"
] }

which results in a couple of compilation errors:

Some errors have detailed explanations: E0308, E0433, E0599.
For more information about an error, try `rustc --explain E0308`.
error: could not compile `identity_credential` (lib) due to 4 previous errors

I have quickly resolved them a couple of weeks ago myself just to make it work (see this).
