[Feature Request] Add lyric to gameplay layout

[Cierra-Runis]

I want to show lyrics when I playing osu, could it possible?

Should be possible, I'll try this later, but it's kinda out of the design.

The lyric feature is designed to be used as a plugin for the Hikariii player, displaying during the game means we need to create the instance out of the player, which is not what I originally designed to do.
