Correct Public key

For correct address change code from PkMaker.py 87 line:
```
	publicKey = "\04" + str(vk.to_string())
	ripemd160 = hashlib.new('ripemd160')
	ripemd160.update(hashlib.sha256(codecs.encode(publicKey)).digest())
```
to:
```
    publicKey = "04" + vk.to_string().hex()
    ripemd160 = hashlib.new('ripemd160')
    ripemd160.update(hashlib.sha256(bytes.fromhex(publicKey)).digest())
```
