Efficient Port Forwarding Configuration for Multiple Ports in UTM iOS

The port forwarding feature in UTM iOS is a valuable tool for exposing services running within a virtual machine to the external network.

**Configuration**
* UTM Version: 4.5.1
* OS Version: 14.6
* Device Model: iPhone 6s
* Is it jailbroken (name jailbreak used)? [checkra1n](https://checkra.in/releases/0.12.4-beta)
* How did you install UTM? [following the UTM Documenation with Cydia](https://docs.getutm.app/installation/ios/#jailbroken-devices)

**Suggestion:**
Implement a mechanism to enable efficient port forwarding configuration for multiple ports. This could involve:
* Port Range Forwarding: Allow specifying a range of ports to forward, such as "80-85, 100-106, 3000-3100".
* Configuration File Support: Enable the ability to define port forwarding rules in a configuration file (e.g., .txt, .config).
