chunkView Unmarshal exception

[vic-dayou]

The main network blcok 70249973 already supports secp256k1 algorithm,
but sdk still does not support it, currently chunkView Unmarshal exception。

func WrapRawKey(keyType PublicKeyType, key []byte) (pk PublicKey, err error) {
	switch keyType {
	case KeyTypeED25519:
		if len(key) != ed25519.PublicKeySize {
			return pk, ErrInvalidPublicKey
		}

		pk[0] = RawKeyTypeED25519
		copy(pk[1:], key[0:ed25519.PublicKeySize])
		return
	case KeyTypeSECP256K1:
		// TODO!
		return pk, fmt.Errorf("SECP256K1 is not supported yet")
	}

	return pk, ErrInvalidKeyType
}

Should be solved by #30. Can you confirm if this works for you?
