Typescript did:peer

This is a typescript implementation of the did:peer method.

Currently it more correctly aligns with the python peerdid implementation of the method. Work is required to update the did:peer method to be conformant with did-core and since this was created to interoperate with other did:peer didcomm participants interoperability has been chosen over spec correctness.

• Supported verification materials (input and in the resolved DID Document)
  • 2020 verification materials (Ed25519VerificationKey2020 and X25519KeyAgreementKey2020) with multibase base58 (publicKeyMultibase) public key encoding.
  • JWK (JsonWebKey2020) using JWK (publicKeyJwk) public key encoding 2018/2019 verification materials (Ed25519VerificationKey2018 and X25519KeyAgreementKey2019)
  • using base58 (publicKeyBase58) public key encoding.
