Add support for ESP32 BTLE presence tracking via NAME requests

**Describe the problem you have/What new integration you would like**
Right now, the BLE tracker does not support devices which issue a random MAC address, such as a phone or tablet.

**Please describe your use case for this integration and alternatives you've tried:**
The built-in "bluetooth_tracker" in HA works properly, as long as the MAC address of the device is known.
It would be nice for the ESP32 tracker to be able to detect the devices if the MAC address is known, even if it broadcast a random address.
This way, multiple presence trackers can be placed throughout the hose, to avoid dead-spots.

**Additional context**
There is another project which does something similar here: [https://community.home-assistant.io/t/monitor-reliable-multi-user-distributed-bluetooth-occupancy-presence-detection/68505](https://community.home-assistant.io/t/monitor-reliable-multi-user-distributed-bluetooth-occupancy-presence-detection/68505)
