aegisub-arch1t3cht: init at feature_12

[wegank]

Reintroduction of arch1t3cht's fork from #359027, until Aegisub absorbs all its features.

I'll create another PR to bump Aegisub to 3.4.1, see https://github.com/TypesettingTools/Aegisub/releases/tag/v3.4.1.

It seems best to just stick with one version of Aegisub for now, I think; I’d especially not want to see the expression forked like this.

I personally believe that we should just use arch1t3cht’s for now, since I don’t think the TypesettingTools version yet offers any compelling advantage over it; probably around 3.5.0 it would make sense to think about moving over as they integrate some of the feature work. But I think even just having the TypesettingTools version alone is preferable to having two separate packages.

One of my concerns is that arch1t3cht/Aegisub seems to be virtually frozen since a month ago, while TypesettingTools/Aegisub is actively receiving PRs. While Aegisub 3.4.1 doesn't bring any editing features that the other doesn't have, it certainly gains much better i18n support in at least two languages. I'd probably be less hesitant to switch to arch1t3cht's fork if the changes were backported...

Fair enough. I definitely think that moving to TypesettingTools as soon as they start to meaningfully catch up makes sense, and I wouldn’t expect arch1t3cht’s fork to have continued momentum at this point given the movement on that, but I am okay just sticking with the TypesettingTools status quo if it’s your preference. We packaged the dead wangqr fork for long enough that waiting a bit longer for functionality seems okay.
