ASDFMovie Cave Sounds

Completely reworked all the sounds in the pack, they no longer contain reverb

Number of sounds has been increased from 122 -> 308 (making the sounds.json was a PAIN)

Due to file compression, pack size has been cut from 20MB to 10MB

Adjusted pack flavor text to account for the additional sounds

Adjusted subtitles to display on 1.21 since the subtitle key for cave sounds was changed from subtitle.ambient.cave to subtitle.ambient.sound for no reason, so this pack no longer uses a lang file for the subtitles
