Include ffmpeg extensions for some audio formats (#109)
Related to #103

Adds ffmpeg decoder module to support a few extra audio formats such as
AC3, EAC3, DTS, & TrueHD.

This increases the apk size by about 5.4mb (release 17.4mb->22.8mb), but
definitely worth it for the added support.

# Wholphin developer's guide
See also the [Contributing](CONTRIBUTING.md) guide for general information on contributing to the project.
## Overview
This project is an Android TV client for Jellyfin. It is written in Kotlin and uses the official [Jellyfin Kotlin SDK](https://github.com/jellyfin/jellyfin-sdk-kotlin) to interact with the server.
The app is a single Activity (`MainActivity`) with MVVM architecture.
The app uses:
* [Compose](https://developer.android.com/jetpack/compose) for the UI
* [Navigation 3](https://developer.android.com/guide/navigation/navigation-3) for navigating app screen
* [Room](https://developer.android.com/training/data-storage/room) & [DataStore](https://developer.android.com/topic/libraries/architecture/datastore) for local data storage
* [Hilt](https://developer.android.com/training/dependency-injection/hilt-android) for dependency injection
* [Media3/ExoPlayer](https://developer.android.com/media/media3/exoplayer) for media playback
* [Coil](https://coil-kt.github.io/coil/) for image loading
* [OkHttp](https://square.github.io/okhttp/) for HTTP requests
## Getting started
We follow GitHub's fork & pull request model for contributions.
After forking and cloning your fork, you can import the project into Android Studio.
You need a compatible Android Studio version for the configured AGP. This is generally `Narwhal 3 Feature Drop | 2025.1.3` or newer. See https://developer.android.com/build/releases/gradle-plugin and [`libs.versions.toml](./gradle/libs.versions.toml).
### FFmpeg decoder module
The app ships with [media3 ffmpeg decoder module](https://github.com/androidx/media/blob/release/libraries/decoder_ffmpeg/README.md).
It is not required to build the extension in order to build the app locally.
You can build the module on MacOS or Linux with the [`./build_ffmpeg_decoder.sh`](./build_ffmpeg_decoder.sh) script. You must have the [Android NDK](https://developer.android.com/ndk) installed.
