Xiaomi X20 Max

[SenshiM]

Describe the bug
The new Xiaomi X20 Max robot vacuum (model: xiaomi.vacuum.d109gl) is currently unsupported by the library. When attempting to integrate it via Home Assistant (using the xiaomi_cloud_map_extractor custom component which relies on python-miio), the device is not recognized, throwing an "unsupported model" warning, followed by authentication and timeout errors.

Version information (please complete the following information):

• OS: Home Assistant OS (Logs indicate Python 3.13 environment)
• python-miio: N/A (Running via Home Assistant custom integrations)

Device information:
If the issue is specific to a device [Use miiocli device --ip <ip address> --token <token> info]:

• Model: xiaomi.vacuum.d109gl
• Hardware version:

Not displayed in Mi Home app

• Firmware version: 4.5.6_0406

To Reproduce
Steps to reproduce the behavior:

1. Setup a xiaomi.vacuum.d109gl device on the local network.
2. Attempt to connect or extract data (like the map) using its IP, Token, and Xiaomi cloud credentials.
3. Observe the logs.

Expected behavior
The device should be recognized as a valid vacuum model, and the local token/cloud authentication should allow successful data extraction without timing out.

Console output
Here is the output from the Home Assistant logs showing the failure:
