Crashing when archiving shows with duplicate subtitles

[Niklashere]

Describe the bug If archiving a show that contains the same subtitles with the same name multiple times, the download crashes. This issue has been persistent since version 3.6.0 and upwards. Version 3.5.2 is the last version without the issue.

Example with https://www.crunchyroll.com/de/watch/GRQW94KQR/the-lost-turnabout Downloading subtitles en-US (CC) [Video: #2], en-US (CC) [Video: #2]

Example with https://www.crunchyroll.com/de/watch/GYE5MWEQR/resolve: Downloading subtitles de-DE, en-US, en-US (CC), en-US (CC), es-419, fr-FR, it-IT, pt-BR, ru-RU

To Reproduce

$ crunchy-cli archive --credentials "XYZ:XYZ" -o "test.mkv" https://www.crunchyroll.com/de/watch/GRQW94KQR/the-lost-turnabout

Expected behavior It should download one of the subtitles if video tracks get merged or both subtitles for each video track if no merge is happening.
