forge_did 0.1.3

### Intro
`forge_did` implement by `Rust`. [Forge_wallet](https://crates.io/crates/forge_wallet) core implementation.

Generate `forge did` from pk, or sk, or pk hash. `forge did` example `did:abt:zNYm1gM23ZGHNYDYyBwSaywzTqLKoj4WuTeC`. Prefix `did` means the string is a `DID`, `abt` means the did is `forge did`. `zNYm1gM23ZGHNYDYyBwSaywzTqLKoj4WuTeC` is address.

### API
 - `get_did_by_sk(sk: &[u8], did_type: &Option<DidType>) -> Result<String>`
 - `get_did_by_pk(pk: &[u8], did_type: &Option<DidType>) -> Result<String>`
 - `get_did_by_pk_hash(pk_hash: &[u8], did_type: &Option<DidType>) -> Result<String>`

### Usage
```rust
    // generate key pair
    let (sk, pk) = forge_signer::get_key_pair(Some(forge_signer::SignType::Ed25519));
    let did_type = create_did::DidType{
        role_type: Some(RoleType::Account),
        key_type: Some(KeyType::Ed25519),
        hash_type: Some(HashType::Sha3),
    }
    let did_by_sk = forge_did::get_did_by_sk(&sk, &Some(w_type.to_owned()))?;
    let did_by_pk = forge_did::get_did_by_pk(&pk, &Some(w_type.to_owned()))?;
    // did_by_pk example: "did:abt:zNYm1gM23ZGHNYDYyBwSaywzTqLKoj4WuTeC";
    assert_eq!(did_by_sk, did_by_pk);
```
