Need to create different Custom Exceptions for different kind of errors

[justdvnsh]

Currently, there are 4 major types of errors which can occur in the app.

• No internet
• Could not parse (when the parser is unable to parse some response -> completed)
• 404 Exception (as the manga page is added we changed the search and genre page to show manga along with the animes. However, in some cases -> Like a genre is present in manga but not in Anime, we'll get a 404 response. The app crashes at that point. We need to handle that and show appropriate response to the user)
• Source error (When the app is not able to parse or play any video)
