Description

**Describe the problem you have/What new integration you would like**
- Similar to the [LD2410](https://esphome.io/components/sensor/ld2410.html) Module, the [LD2410S](https://www.hlktech.net/index.php?id=1176) is a Ultra low Power 24GHz Radar Sensor. But it works with baudrate 115200 which is the smaller problem. Since it uses a different protocol, it does not work with the current integration.

**Please describe your use case for this integration and alternatives you've tried:**
- Radar sensor with very low power consumption (~0.1 mA)

**Additional context**
- User Manual: (Communication protocol is in chapter 5) https://drive.google.com/drive/folders/1wC8KC-DaNavNbpeVouZ1HdiBzZ9YrAcg
- Device: https://www.hlktech.net/index.php?id=1176
