support for two new buttons as in newpipe

[Wjxfi]

One button has three modes - song repeat, playlist repeat, return to no repeat mode. The second button closes the notification.

addition. I noticed that it is impossible to listen to music because of several buttons (It only rewinds for 10 seconds, that's awful), so do what I ask below. the <- and -> buttons should work as in newpipe. https://user-images.githubusercontent.com/113500363/225999891-d32e1d22-5b45-45d2-a8e3-b53e001f4d85.mp4

Probably won't be done in the near future. I'm using a library that handles this and it's handling of playlists is not great. I'd have to either modify the library or re-do the player using a more barebone player and implement all the options myself.
