demo of full authorization flow

[andorsk]

a sample demo with a full authorization flow. This is moved from https://github.com/TBD54566975/ssi-sdk/pull/123. In this, 3 actors are presented:

1. A university
2. A student
3. An employer

The situation is simple: A student graduates from Example University, and Employer now wants to hire the student. This flow outlines how the VC flow works, between the holder, issuer, and verifier. Below is an example of the flow.

There is a basic authorization check later, which checks if the employer is OK with the student's VC claims. This is intended to be an explanatory demo, not a production use case.

@decentralgabe can you take a look at this and let me know if at least the flow is correct and there's nothing wrong conceptually with the demonstration?

[andorsk]

@decentralgabe yea...we can break it up into multiple files. Good idea. Thanks for the comments.

[andorsk]

I need to eventually bring this back to life. Sorry, been caught up with other things.

[andorsk]

Based on https://github.com/TBD54566975/ssi-sdk/pull/164 will move over to use_cases.

@decentralgabe I think this example will work. I've incorporated the feedback provided. There's things that I would like to improve, in later PR's, but for now if possible I'd like to just get this example in, and improve the example later. It's been 29 days this PR's been open now 🙄 ( mia culpa. it just slid off my radar )

Can you take a look when you have a chance, and we can discuss what changes would be needed for a merge? I'd like to limit future work on it, but I don't want to scrap this work either as it accomplishes I think, it's primary goal of being a simple example to demonstrate a full issuance and verification flow.

I think this with the apartment use case: https://github.com/TBD54566975/ssi-sdk/tree/main/example/use_cases/apartment_application are reasonable reference points for a beginner.

@decentralgabe please check out the comment above re: my position on this PR.

noticed a number of package names with underscores. I know there are some already with this pattern (which should be corrected) - but the go style guide advises avoiding it https://go.dev/blog/package-names

Good call out. Refactoring.
