feat(anoncreds): add legacy indy credential format

[TimoGlastra]

Adds a LegacyIndyCredentialFormat class to the AnonCreds package that can handle the current indy format as described in RFC 0592. This doesn't support the new ledger agnostic anoncreds yet, but it does implement the old format with the new APIs we have.

I've written some initial tests using this service and the new anoncreds apis implemented using the indy-sdk. I'll add more in follow up prs when the api and proof format are added.

Partially fixes #1130, but the proof format is still todo. This will actually be a lot more work as we still need to make the proof interfaces dynamic and allow for dynamic registration of proof protocols

[TimoGlastra]

Question: should we call it LegacyIndyCredentialFormat or just IndyCredentialFormat? Maybe it's too soon to update the naming to legacy?

Nothing major, just some small points.

I think legacy is fine. We are going to name it legacy anyways in the near future and it shows the intention we have with the format.

Just one comment about creating an issue on anoncreds-rs. Otherwise it looks good to me.
