[TEMPLATE] Music resource pack for easy modification

Added several new .ogg files such as: yakusoku.ogg wet_hands.ogg watcher.ogg sweden.ogg subwoofer_lullaby.ogg puzzlebox.ogg pokopoko.ogg oxygene.ogg minecraft.ogg mice_on_venus.ogg living_mice.ogg komorebi.ogg key.ogg haggstrom.ogg featherfall.ogg dry_hands.ogg eld_unknown.ogg danny.ogg deeper.ogg clark.ogg ballad_of_the_cats.ogg concrete_halls.ogg dead_voxel.ogg warmth.ogg aria_math.ogg biome_fest.ogg blind_spots.ogg dreiton.ogg haunt_muskie.ogg taswell.ogg the_end.ogg alpha.ogg

As of 1.21 the game now uses named files in place of music instead of the old naming like nuance1-4 or piano1-3 etc. so they got renamed to .ogg_old file extension since they're unused now.
