Add streaming Sound assets

[RiscadoA]

Sound assets should be optionally streamable so that we can play music.

@diogomsmiranda @Dageus this isn't implemented yet. Streaming sound assets means not loading the entire sound asset at once, and instead, fetch one block at a time. This is important for stuff like music so that you don't waste memory just to keep around 10 mins of music, for example.

we would need to add a flag to the ma_sound_init_from_file:
ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound);

The amount of data loaded into memory is 2 seconds by default.

It isn't that simple sadly because we should use our filesystem abstraction instead of accessing the real filesystem directly as miniaudio does. The music file might be inside a .zip, or even embedded in the executable binary itself
