Support alternative versions of TV series episodes like with movies

Is your feature request related to a problem? Please describe

I am unable to play alternate versions of a TV series episode using the jellyfin-roku client, and the client does not proactively display when alternate versions are available (as compared to, for example, the '2' overlay that appears in the Jellyfin web app when viewing an episode with multiple versions available). If I select an episode that I know has an alternate version, and hit the star button on the remote, I receive a menu screen that appears to allow me to choose the alternate version, however the Roku client always plays the same version no matter what is selected on that screen. It seems to play whichever version is listed first, which seems to be the first one when sorted alphabetically.

Describe the solution you'd like

When selecting an alternate version of a TV series episode from the star menu, the jellyfin-roku client should play the selected video stream. It would also be nice to see the '2' overlay indicator (or any other indicator) to show that multiple versions are available.

Describe alternatives you've considered

An interface similar to the one used for movies to select alternate versions would be even better, but just having it select the correct file when manually chosen from the star menu would be good.

Additional context

The alternate episode versions, in this case, were linked using the only way possible in the web app, which is by clicking into the first episode, selecting the alternate version from the "More from Season X" section, and then merging them by selecting "Group Versions". The web app properly plays the alternate version when selected. Tested using the current release version of the jellyfin-roku client.
