Add support for Alpicool Fridge

**Describe the problem you have/What new integration you would like**
I wanna that ESPHome support [Alpicool](https://www.alpicool.com/index.html/) refrigerators.

**Please describe your use case for this integration and alternatives you've tried:**
Alpicool refrigerators are the most used for people with camper vans or caravans due to their quality/price ratio. These refrigerators have Bluetooth to be controlled through an [APP](https://play.google.com/store/apps/details?id=com.alpicoolneutral.fridge.controller&gl=ES). It would be great to be able to control the on/off and temperature control from anywhere.

**Additional context**

The request names the Alpicool website and Android app but provides no repository files, tests, or Bluetooth protocol details. Start by examining those references to determine the device protocol and supported controls; done requires an agreed integration scope and validation approach.
