[Flatpak] .wma files are not supported

[Sky-NiniKo]

How to reproduce

1. Install resonance through Flathub
2. Have a .wma file (you can use ffmpeg (CLI) or FFaudioConverter (GUI))
3. Add it to your library
4. Try playing the track

Possible solution

It's seem like a missing dependency for gstreamer.

ASF (format used in .asf, .wma and .wmv files) parser for GStreamer is available in "Ugly" plug-in set: https://github.com/GStreamer/gst-plugins-ugly/tree/master/gst/asfdemux.

I couldn't find how to include those plugins in Flatpak manifest, but they can be instead simply accessed from the host, like how Bottles does it: https://github.com/bottlesdevs/Bottles/blob/main/com.usebottles.bottles.yml#L23
