Problem Description

As brought up in #260 and seemingly still the case, FreeTube doesn't support importing OPML files from at least some RSS readers.

Proposed Solution

Support for OPML files from RSS readers for importing channel subscriptions would be appreciated, particularly where there are a lot of channels and no way to export another format that FreeTube supports.

Alternatives Considered

The docs suggest asking for support for a format FreeTube supports to be implemented, but that is not always possible (my preferred RSS client, RSSOwlnix, is not actively under development for instance).

Could you please provide some example files. If you feel uncomfortable sharing your own subscriptions, you could use some of the official YouTube's own channels instead e.g. https://youtube.com/@YouTube and https://youtube.com/@YouTubeMusic.

Sure, I'll share a file with a few subscriptions. GitHub doesn't let me upload OPMLs so I'll share the contents directly.

Interesting from just looking at the code and that file, it should already work.

Are you getting any specific error messages during the import?

TypeError: Cannot read properties of undefined (reading 'name')

One or more subscriptions were unable to be imported.
