[Feature request]: Update interface address parser to support default WG configs

[XFox111]

It would be great if WireSockUI had Interface/Address support to be a plain IPv4 address (without network prefix)

Justification

Default WireGuard configs have their Interface/Address set as plain IPv4 address without CIDR prefix:

[Interface]
Address = 10.15.15.7
PrivateKey = ABCDEF123456...
ListenPort = 51820
DNS = 10.15.15.1
...

But even though WireSock CLI is completely fine with it, WireSockUI requires it to include a CIDR prefix:

[Interface]
Address = 10.15.15.7/32
PrivateKey = ABCDEF123456...
ListenPort = 51820
DNS = 10.15.15.1
...

Besides, WireSockUI gives a pretty vague message when encountered the issue, which, if you don't know what the issue really is, can be quite frustrating:

"Address" in "Interface", invalid address "10.15.15.7"

Besides, it doesn't give me any info if I click on it:

Plus, if I try to connect to the peer using system tray icon - it works just fine:

Alternatives

Alternatively, it would be great to make the error message more clear. I don't add new configs often, so when I do, I have a hard time remembering to add the prefix.

Thank you for bringing this to my attention. WireSockUI incorporates a unique syntax checker that differs from the one used in WireSock VPN CLI. I will investigate this issue and aim to eliminate this limitation.

I have addressed this issue in v0.2.2. Could you please give it a try?
