feat: adapt to latest did core spec and libs (#61)

* chore(deps): update deps * feat: adapt to latest did core spec BREAKING CHANGE: new did core spec uses different format for DID documents and resolution. BREAKING CHANGE: Now using ethers.js which means that providers and signers may have a different API BREAKING CHANGE: default export was removed closes #50 closes #59 closes #21 closes #49 closes #51 closes #52 closes #57 closes #58

-This library conforms to [ERC-1056](https://github.com/ethereum/EIPs/issues/1056) and is intended to use Ethereum addresses as fully self-managed [Decentralized Identifiers](https://w3c-ccg.github.io/did-spec/#decentralized-identifiers-dids) (DIDs), it allows you to easily create and manage keys for these identities.  It also lets you sign standards compliant [JSON Web Tokens (JWT)](https://jwt.io) that can be consumed using the [DID-JWT](https://github.com/uport-project/did-jwt) library.

-Ethr-DID provides a scalable identity method for Ethereum addresses that gives any Ethereum address the ability to collect on-chain and off-chain data. Because Ethr-DID allows any Ethereum key pair to become an identity, it is more scalable and privacy-preserving than smart contract based identity methods, like our previous [Proxy Contract](https://github.com/uport-project/uport-identity/blob/develop/docs/reference/proxy.md).

-This particular DID method relies on the [Ethr-Did-Registry](https://github.com/uport-project/ethr-did-registry). The Ethr-DID-Registry is a smart contract that facilitates public key resolution for off-chain (and on-chain) authentication. It also facilitates key rotation, delegate assignment and revocation to allow 3rd party signers on a key's behalf, as well as setting and revoking off-chain attribute data. These interactions and events are used in aggregate to form a DID's DID document using the [Ethr-Did-Resolver](https://github.com/uport-project/ethr-did-resolver).

 ## DID Method
 
-A "DID method" is a specific implementation of a DID scheme that is identified by a `method name`. In this case, the method name is `ethr`, and the method identifier is an Ethereum address.

 To encode a DID for an Ethereum address, simply prepend `did:ethr:`

+access to the private key). This instance will not have the ability to sign anything, but it can be used for a subset of
+actions:
+
+* provide its own address (`ethrDid.address`)
+* provide the full DID string (`ethrDid.did`)
+* lookup its owner `await ethrDid.lookupOwner()`
+* verify a JWT `await ethrDid.verifyJwt(jwt)`

+### Multiple ethereum networks
+EthrDid can be configured to control a DID on any ethereum network.
+To do this, you mush specify the `chainNameOrId` during construction.
+Example:
+`new EthrDid({ address, 'rsk' }).did`
