Can't extract more than one sub track per language unless overwrite/force is enabled

[guiweber]

Tested on V 0.1.11

When launching via CLI with option --all, only the "regular" sub track for a language is extracted even if the file has multiple sub tracks of the same language (forced, sdh). Launching with -a yields the same result. Specifying languages or not doesn't change anything. However, if the -f flag is added, then more than one track for the same language are extracted.

The issue also happens when using the API. Setting one_per_lang=False has no effect unless configuring overwrite=True.

After playing a bit more with the API, I noticed that the issue also happens with the API if "overwrite=False" (tested without any .srt files already present in the directory).

Works:
options = Options(languages={"en"}, overwrite=True, one_per_lang=False)

Doesn't work:
options = Options(languages={"en"}, overwrite=False, one_per_lang=False)

Also confirmed that adding -f in the CLI makes it work. Updated the main issue description.
