a Create a new Poly1305 MAC object.
Args:
key (bytes/bytearray/memoryview):
The 32-byte key for the Poly1305 object.
cipher (module from ``Crypto.Cipher``):
The cipher algorithm to use for deriving the Poly1305
key pair *(r, s)*.
It can only be ``Crypto.Cipher.AES`` or ``Crypto.Cipher.ChaCha20``.
nonce (bytes/bytearray/memoryview):
Optional. The non-repeatable value to use for the MAC of this message.
It must be 16 bytes long for ``AES`` and 8 or 12 bytes for ``ChaCha20``.
If not passed, a random nonce is created; you will find it in the
``nonce`` attribute of the new object.
data (bytes/bytearray/memoryview):
Optional. The very first chunk of the message to authenticate.
It is equivalent to an early call to ``update()``.
Returns:
A :class:`Poly1305_MAC` object
