Include Component for Hiking DDS238-4 W and DTS238-7 Wifi Energy Meters

**Describe the problem you have/What new integration you would like**

A fellow coder forked the repo and added a component to interface with Hiking DDS238-4 W and DTS238-7 Wifi Energy Meters (and potentially other similar compatible units).
I have worked with him to test and debug the integration, and have been using it for more than two years without issues.
I have noticed that there was no pull request, so the component has not been integrated into the release of esphome, and an external reference is needed.
His code is located here:
https://github.com/rodgon81/esphome/tree/dev/esphome/components/dxs238xw

**Please describe your use case for this integration and alternatives you've tried:**

Whereas the code does work, I have noticed that latest logs indicate that some code included in the component will be deprecated, so the code may no longer work starting on 2025.11 release:

```

Would it be possible to pull the code and make the component available in the main release branch, potentially fixing the outdated reference?
I will do my best to get in contact with the original developer.
