1.20 update

updated pack format to 15

tribute to darian

darian left for school last month, so i'm adding his music as a tribute to him, we will miss you 😔❤

converted stereo sounds to mono

as i've learned, stereo plays the sound at the player but mono plays where the sound comes from (eg. the jukebox), and some records do this so this is fixed in this update
