Using ESPNOW for the pump controller

Add the following to your esp relay config:

espnow:
  peers:
    - "{MAC ADDRESS OF THE FLOOR HEATING CONTROLLER}"
  auto_add_peer: False
  on_receive:
    - lambda: |-
        std::string received_data((const char*)data, size);
        ESP_LOGI("espnow", "Received ESP-NOW message: %s", received_data.c_str());

        if (received_data == "PUMP_ON") {
          id(relay).turn_on();
          ESP_LOGI("espnow", "ESP-NOW: Executed PUMP_ON command.");
        } else if (received_data == "PUMP_OFF") {
          id(relay).turn_off();
          ESP_LOGI("espnow", "ESP-NOW: Executed PUMP_OFF command.");
