Add Nightcore mode feature!!

[Christ0_F]

A fun little modification to the listening experience similar to controlling playback speed except Nightcore mode speeds up and changes the pitch of the song up like those Nightcore remix on YouTube. Example for something with similar feature: the Musico bot on Discord with the "/nightcore" command. I thought it would be fun when sometimes you're bored with the song and wanted to change things up a bit. Maybe you could also customize the speed and the pitch of the song however you want too or just select the default speed and pitch preset.

Sorry if my suggestion is unclear 🙏🙏

This!! They also should allow Daycore/Slowed as well. Really preferred cause I love Nightcore/Daycore of songs so it would be a cool feature.
