Implement Out of Band Attachment Handling
Feature Description
The OOB protocol is currently implemented and demonstrated for the exchange of a connection invitation. It should also be possible to issue a credential and request a proof in this OOB manner.
Before this can be implemented the ACA-Py OOB protocol must be extended to handle these pathways at the agent level. We could create a P.R for this ourselves for this capability.
See this if block https://github.com/hyperledger/aries-cloudagent-python/blob/653a4c2c4d19e1e3a0b6b89467affcea81827434/aries_cloudagent/protocols/out_of_band/v1_0/manager.py#L258
Started with the testing of the OOB attachments in this branch. Seems like AcaPy 0.5.6 does not currently support the credential-offer and present-proof message types
