Track Title in audio and subtitle tracks

it would be very helpful for fastflix to show the track title from the file for the audio and subtitles so its easier to disable ones you don't want without having to check with mediainfo

The issue names no files or tests. Start by locating the FastFlix UI entry point that lists audio and subtitle tracks, then trace where track metadata is read from the input file. Done means those lists show each track's title so unwanted tracks can be disabled without consulting MediaInfo.
