Added Quest Launcher mod browser

- Introduced new drawable resources for user and warning icons.
- Created layout files for mod browser items, loading indicators, and the main mod browser page.
- Implemented IDs for resource referencing in the layout.
- Added unit tests for GameBanana API interactions, ensuring proper parsing of mod data and error handling.
- Developed Rust module for handling mod archives, supporting extraction of 7z and RAR formats with error checking.
