feat(patch): more subtitle sizes / os independent caption settings

[castdrian]

Application

YouTube

Issue

Currently youtube makes use of the OS settings to define caption style and size. However the OS defaults are only 3 sizes which results in too big or too small subtitles depending on device and OS version

Patch

Ideally OS independent subtitle settings, for at least the size of it, because the OS predefined size options are rendered either too big or too small on my device, maybe a pinch to zoom alongside the functionality that was requested in another open issue, namely the one that requests moving subtitles around by dragging them

Motivation

The Android default size settings aren't refined enough to achieve a proper resizing/can't be set per-app so every application is using the same caption size and style unless it is designed to use its own caption settings
