Feature Request: "Zoom to Fill" Option & Dynamic Sidebars Matching Video Colors

[dymarow]

Hi, thank you for the great work on M3UAndroid!

I'd like to request a feature similar to what's available on the YouTube mobile app:

1. Zoom to Fill: An option to pinch the video to zoom in and fill the screen, cropping letterboxed content to remove black bars.

2. Dynamic Sidebars: When playing vertical or non-fullscreen videos, add blurred or color-matched sidebars to the left and right, dynamically generated based on the video's edge colors. This makes the viewing experience more immersive and visually pleasing.

I'll attach a demonstration video to show how this looks in practice.

Thanks for considering!
