Please describe your bug

SDH = Subtitles for the Deaf and Hard of Hearing

The server currently handles subs, and other tracks in a side-by-side manner.
It recognizes, default, forced, but not SDH (upper or lower or any case)

https://jellyfin.org/docs/general/server/media/external-files.html

e.g.

a.mkv
a.default.en.srt
a.forced.ru.srt
a.en.dts
a.ru.ac3
...

It does not yet understand SDH.
