[FEATURE] add possibility to play .wav files

[Pauler221]

First of all thank you for an awesome music player! I really enjoy it!

It would be really convenient if you'd add the possibility to play .wav files and preferably other formats as well like .ogg etc.

Ah yes, thanks for your request! Tho symphonica soon will be archived since I'm baking a new project from the ground now. Maybe you can cope with the current version and wait till https://github.com/AkaneTan/Gramophone is released? I will surely add your requested feature in gramophone's future version.
