ESP32 Camera Web Server - Basic Auth

**Describe the problem you have/What new integration you would like**
No authentication option for the [ESP32 Camera Web Server Component](https://esphome.io/components/esp32_camera_web_server.html) serving the cameras content.

**Please describe your use case for this integration and alternatives you've tried:**
Both in a development environment and in a homelab use case (ex. monitoring 3D printer), it feels like a bad practice leaving an HTTP endpoint that serves realtime images completely without authentication. I wasn't able to find any alternatives from within ESPHome - only compiling the ESP32 code from outside of ESPHome.

**Additional context**
The ESP32 Camera Web Server component has no option for authentication, leaving the endpoint widely open. While HTTP basic auth may be easily compromised with network sniffing, it is at least an additional layer of security.

Start by reading the ESP32 Camera Web Server component documentation linked in the request and identify how its HTTP endpoint is exposed. Done means the component offers an authentication option and the camera endpoint requires valid HTTP Basic Authentication instead of remaining openly accessible.
