Description
This PR will try to find channels that may have been deleted when your subscriptions get loaded (except when using Invidious that's not in RSS) and it allows you to load the subscription information that is saved when viewing a channel page

Screenshots (if appropriate)

Testing (for code that is not small enough to be easily understandable)
Has this pull request been testedZ

I was able to get the links of two channels that were deleted for different reasons and I tested:
refreshing the Subscription page with

• Local API + RSS
• Local API + RSS Disabled
• Invidious + RSS
• Invidious + RSS Disabled (not currently useful)

I also tested navigating to the channels with invidious and local api and was able to unsubscribe

Desktop (please complete the following information):

• OS: Windows
• OS Version: 10
• FreeTube version: 0.16.0

Additional context
Test Subscription File (change extension from txt to db):
Test Subscriptions.txt

seems to be an issue with having fallbacks enabled, I'll look into that. Edit: nvm

I really like how u have implemented this PR. LGTM!

I left a few suggestions, happy to discuss the "Error Channels" vs "channels with errors". I don't have any channels with erros so I can't test this, however the rest of the code looks good to me.

If you want to test this, I included a txt file in additional context (if you change the extension to db then you should be able to import the subscription)

Everything LGTM! @ChunkyProgrammer I have one last question though before i approve. I know that only using the Invidious API doesnt show the blocked channels banner. Is it possible to show the banner when the Invidious API is primary and u have a fallback to the Local API?

This won't happen. Invidious only returns an empty video list when rss is not being used and won't throw an error so it won't fallback. I don't think adding channels with no videos to the error list would be the best idea. Clicking on the channel on the side will still allow them to unsubscribe they just won't be notified of that channel causing errors

That's fair. LGTM!
