Include BTHome gateway

[NdK73]

Hi.

I think it could be really useful to have support for BTHome (passive reporting of BLE advertising packets), since the ESP32 RF remains otherwise unused. In ESPHome it's really easy to add:

esp32_ble_tracker:

bluetooth_proxy:
  active: true

but IIUC ESPHome support is discouraged.

Tks, Diego

Hello.
Unfortunately, I am not aware of BTHome implementations in the form of a library that could be added to an existing project.
ESPHome is set up quite differently, and unfortunately it's not possible to just add something from it.
