Add Offline Caching in the Manga Page

[justdvnsh]

Room has been added to the project. Now, we need offline caching for the manga page. The method would be pretty straight forward. The very time network request is made and then first saved into the database. Then the data on the manga screeb would actually be coming from the database everytime instead of network directly.

This would help us achieve 2 things ->

• User would only the loading screen for the first time he enters the app.
• Since the page is cached, we can make the network request and update the home screen before the user enters the app (using work manager or something like that)
