Describe the problem you'd like to have solved

We have a use case in a highly regulated industry where the IDP is configured to use FAPI 2.0 but WITH JAR (OIDC JWT-signed authorization requests).

The SDK does not current support a way to enable JAR. Would you be interested in a PR for this?

Describe the ideal solution

It would be great if there were an option to enable JAR or an extension point where the authorization request could be transformed.

Alternatives and current workarounds

Currently we are supporting this use-case by maintaining a fork of the SDK.

Hi @bls 👋
We would appreciate a PR for JAR suoport in the SDK. In addition, your fork could be of much help too (if it's public).
