Artemis .lua support

[DSwizzy]

I can't extract nor convert .lua files to a .ast format, i'm working on a restore uncensored 18+ content for the Nintendo Switch version port of 雲上のフェアリーテイル (Unjou no Fairy Tale) that just recently came out already and while the PC version uses .lua files for the scenario files, the Switch version stuck with the usual .ast files for theirs.

If you can add support for that, it would be very appreciative!
