Encode and decode NDEF message using Xiaomi NFC protocol.

## Usage

```shell
pip install xiaomi-ndef
```

```python
from pyndef import NdefMessage

from xiaomi_ndef import MiConnectData, XiaomiNfcPayload, V2NfcProtocol
from xiaomi_ndef import ndef, xiaomi, handoff, tag

# Example
NDEF_MSG_BYTES = b"..."

# Parse ndef
ndef_msg = NdefMessage.parse(NDEF_MSG_BYTES)

ndef_type = ndef.get_xiami_ndef_payload_type(ndef_msg)
ndef_bytes = ndef.get_xiami_ndef_payload_bytes(ndef_msg, ndef_type)

# Parse ndef payload
mi_connect_data = MiConnectData.parse(ndef_bytes)
nfc_protocol = mi_connect_data.get_nfc_protocol()
nfc_payload = mi_connect_data.to_xiaomi_nfc_payload(nfc_protocol)

# Build new screen mirror record
handoff_ndef_type, handoff_payload = xiaomi.new_handoff_screen_mirror(
    device_type=handoff.DeviceType.PC,
    bluetooth_mac="00:00:00:00:00:00",
    enable_lyra=True
)
handoff_record = ndef.new_xiaomi_ndef_record(handoff_ndef_type, handoff_payload)

# Build new ndef msg
handoff_msg = NdefMessage(handoff_record)
print(handoff_msg.to_bytes().hex())

# Customize xiaomi ndef
XiaomiNfcPayload(
    major_version=1,
    minor_version=11,
    id_hash=0,
    protocol=V2NfcProtocol,
    appData=tag.NfcTagAppData(

                flags=0,
                device_number=0,
                attributes_map=tag.NfcTagDeviceRecord.new_attributes_map([

                    tag.DeviceAttribute.BLUETOOTH_MAC_ADDRESS.new_pair("00:00:00:00:00:01")
                ])
            ),
            tag.NfcTagActionRecord(
                action=tag.Action.CUSTOM,
                condition=tag.Condition.AUTO,
                device_number=0,
                flags=0
            )
        )
    )
