Implement Faster IPv4 Address Retrieval Method

[Carterpersall]

• Implemented a new method to find the user's actual IPv4 address using a recursive mess of .NET witchcraft that somehow ends up being much faster
  • Uses a combination of C# scripts at https://stackoverflow.com/questions/8089685/c-sharp-finding-my-machines-local-ip-address-and-not-the-vms/25553311 which I converted to PowerShell
  • Gets all network adapters using [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces()
    • Checks if each adapter is online, has a gateway address, and is not a loopback adapter
      • Then checks if the adapter is a WiFi or Ethernet adapter using NetworkInterfaceType
        • Then iterates through each Unicast address, and checks if the address is for InterNetwork communication
          • Then checks if the $local_ip variable has already been set, and if not, sets it to the IP returned
            • This is because, under some circumstances, multiple IPs can be returned
              • It grabbed the ZeroTier IP address on my PC, which shouldn't occur
              • This bug also exists with the previous implementation, and I'm not sure if there is an easy way to fix it without manually filtering out specific adapter names
