ffmpeg | branch: master | Marth64 <marth64 at proxyid.net> | Tue Jan 23 20:03:19 2024 -0600| [01388936a8840a4cce0d4fa9862e6f63c59ffd38] | committer: Stefano Sabatini

avformat/avlanguage: add the 6 deprecated DVD languages

There are 6 deprecated ISO language codes that are still valid for DVDs.
This patch allows avlanguage to recognize them correctly. The codes are:
(1) "in" - legacy code for Indonesian, mapped to the modern code
(2) "iw" - legacy code for Hebrew, mapped to the modern code
(3) "ji" - legacy code for Yiddish, mapped to the modern code
(4) "jw" - legacy code for Javanese, published and used as a typoed version of "jv"
(5) "mo" - legacy code for Moldavian, mapped to the inclusive code
(6) "sh" - legacy code for Serbo-Croatian, no modern inclusive code so it is left alone

All of this can be verified from several sources including:
https://en.wikipedia.org/wiki/List_of_ISO_639_language_codes
