[Feature] In-App Proxy Support

[EhsanFox]

Is your feature request related to a problem? Please describe.
For some users, they need to open a VPN or something to use Yukino because the API's and videos are from a server that might be blocked.

Describe the solution you'd like
We can add Support for Proxy in the app, so they can just connect their proxy to the app and only tunnel their app instead of whole pc(You can Check Telegram App for Example)
[and Even Better for API's that fetch data for searching anime/manga, you can create an API server]

Describe alternatives you've considered
Might be a Hard thing to do?

Additional context
None.
