Support for v1.0 of Hedera DID Method

[derek-meeco]

Description:

This update aligns the JavaScript SDK with the Hedera DID Method v1.0.

This updated specification for the Hedera Hashgraph DID Method aligns with the Decentralized Identifiers (DIDs) v1.0 W3C Recommendation, published 19 July 2022.

The specification allows for DID resolution via construction of DID document elements from HCS messages, or from lookup of DID document from IPFS via a CID reference registered via a HCS message.

This is part of HIP-27: DID improvements to offer a broader support and interoperability for the Hedera DID method
