(Scanner) Adds support for the Extend multi-episode format i.e. S01E01-02 (#14064)

[tom80H]

There’s a feature suggestion discussing for Plex to change how multi-episode files are displayed inside the apps.

Display single file multi episode shows in a single item

a way to have Plex display single file multi episode shows in a single item, ex: episode name, Episode 1-2, instead of duplicating it in the display and playing the full file twice. Instead of having to split the files, or only having one of the episodes in the file name, making it seem like im missing something. also: ability to show multi part movies in a way that makes sense, like part 1 and 2 under the same Title, instead of showing it as if there was a duplicate movie.
