ESP32 support ELM (ELM327) OBD2

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

ESP32 has bluetooth which can be used for requests to the car CAN bus via OBD2 adapter.
Also, such requests can be sent through the UART port.

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

The main application case is the collection of vehicle data and transmission over Wi-Fi. For example, through a MikroTik LTAP (mini) access point.
There are alternatives not for this application.
