Flag emoji on mirrors list

[diogob003]

• Group subtitles by language code instead of name
• Show flag and localized name on chose subtitles / mirrors dialog

I'm unsure about it.
Using SubtitleHelper to translate names fix "en -> English", but may group weird names like "English / German" into "unknown".
Adding a flag here seems a bit ugly to me; maybe without the flag it would be better.

Hey, got told to comment here about a subtitle issue. Extensions that have AI alternatives, often named "english (AI)", always appear above normal english, which results in cloudstream automatically picking the AI alternative if you have subtitles enabled, and you have to manually switch on every single episode.

So it would be nice if you could change the sorting to have the original language first, and probably even when there's mutliple numbered alternatives, and anything inside parentheses after normal numbering. Could probably even prioritize a space and lettering beneath a space and numbering as well so if a subtitle is titled "english" or "english 1", they would still be picked before anything titled "english (AI)" or "english AI"

If you're looking for something to test it I'd recommend streamplay-anime, they have AI on pretty much all shows that have english dubs
