[Bug]: Aria2 IPv6 issues

[EveKaczmarek]

Describe the bug.

Hi,

I think I have caught the new bug. Today all Civitai downloads just stopped working and the extension prints "error occured during download" on every attempt. After looking through the FAQ, I traced the problem to aria2 and enabled logging. It just refusing to download anything.

With this in mind, I did a bit of research on the Internet in the hopes of finding something. Apparently, this is a known problem and it's already reported in the aria2 repo aria2/aria2#1549.

For some reason, aria2 decides to use IPv6 even when it's disabled or unreachable, causing this problem.
I see a couple of ways to fix this:

• Disable IPv6 completely. Add "--disable-ipv6" option to completely mitigate this nonsense.
• Add Python exception handling to retry the download without IPv6 if aria2 fails.
• Add an option to the extension settings to disable/enable IPv6. Personally, I think leaving it disabled by default is the safest way.

Thanks.

Steps to reproduce the problem.

1. Open a model card
2. Press "Download model"
3. Notice CivitAI Browser+: Error occured during download line in the terminal

Expected behavior

A model should start downloading
