Potential DIDComm did:peer:2 Spec Compliance Issue

[TheTechmage]

I'm not too familiar with how the DIDPeer DIDs are supposed to work, but according to this comment, it appears that there may be some issues with Peer DID Numalgo 2 generation across libraries between https://github.com/sicpa-dlab/didcomm-rust/ and here. The output is different enough that it has caused a conversion layer to be built to convert the DID between libraries in order to maintain inter-operability. Daniel has submitted a PR to the Spec to make clarifications decentralized-identity/peer-did-method-spec#62 but as of this moment it has not been merged.

Irregardless of the merge status, did:peer:2 DIDs generated by didcomm-rust and didcomm-python are incompatible with each-other when a service endpoint is defined. didcomm-python is expecting a flat servicesEndpoint structure, where-as didcomm-rust is expecting an object.
