    node   : v24.4.0
    fungsi : download audio / video youtube
    note   : video itag18, link download video kadang work kadang gk
             maksimal durasi audio dan video belum di ketahui
             tapi gw test video 24 jam bisa :v,
             audio 24 jam nya jg bisa cuman ada queue processing.
             tapi kalau musik / video common sih rasanya ok ok ajah.
             oh ya support ytmusic juga. masukin aja id nya
