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.

I dont think its the duplicate subtitles because in my example the previous episodes should suffer from the same issue

[Niklashere]

Not sure if that's the reason, but episodes one and two of your example each have one en-US (CC) and en-US. Only episode 3 has two subtitles in en-US (CC). This would reinforce my suspicion further. Perhaps additional testing is required.
