Added support for Nice Digi X1 Smart Lock

Added support for Nice Digi X1 Smart Lock based on @raphaeleduardo42 PR

The sensors and volume/language settings all work, but the BLE unlock doesn't appear to work.

I did reverse engineering on unlocking lock for supporting dp_id 71 and now my lock is working on unlocking.
You need to know the devUnlockId and ins parameters from Tuya IoT platform.
Instruction to get devUnlockId and ins:

• Go to Device Debugging page on Tuya IoT platform, select DP_ID to Ble unlock(with key) and click Search, payload will show in Event Details.
• Go to Cloud API Explorer and select Device Control -> Query Properties, enter device ID and code ble_unlock_check, then click Submit Request, payload will show in result.properties[0].value

The payload from platform is encoded by Base64, the format of payload:

[ xx xx ][ ff ff ][ 31 32 33 34 35 36 37 38 ][ xx xx xx xx xx xx xx ][ 00 ][ 0x ]
[ devUnlockId ][ fixed ][ ins ][ epoch ][ fixed ][ 00 is fine to unlock]

Datapoint value to send by BLE is different format:

[ ff ff ][ xx xx ][ 31 32 33 34 35 36 37 38 ][ 01 ][ xx xx xx xx xx xx xx ][ 00 ][ 0x ]
[ fixed ][ devUnlockId ][ ins ][01][ epoch ][ fixed ][ 00 is fine to unlock]

So I can unlock my lock with following code:

datapoint = self._device.datapoints.get_or_create(
    self._mapping.dp_unlock_id,  """ dp_id for unlock is 71 """
    TuyaBLEDataPointType.DT_RAW
    )
d = "ffff" + devUnlockId + ins + "01" + int(time.time()).to_bytes(4, 'big').hex() + "0000"
new_value = bytes.fromhex(d)

Hope my research can help you for developing this integration.
