Improve verification result details #144
Description
Currently when verifying a VP and the verification fails, it is sometimes hard to get the results from the verification. Instead of throwing errors, it might be useful to build a verification object that includes for each VP the results of the verification and reasons for why the verification failed.
You can work around this by creating a mapping in the presentation verification callback and store what went wrong, but it would be nice if the OID4VP library would take care of this.
