72. tmpfiles.org [uploader]

/* gak tau, pengen aja bikin uploader yg makek stream :v
  base : https://tmpfiles.org
  by   : wolep
  node : v24.11.1
  note : file uploader, powered by tmpfiles.org
         bukan skrep karena udh disediain apinya :v
         kode nya bisa di pakek upload file dengan
         stream, buffer, custom name, custom extension
         auto pick extension pakai library file-type
         auto fallback ke ekstensi bin kalau gagal
         nih paramnya
         {
         filenameWithoutExtension = opsional,
         stream = required *,
         buffer = required *,
         ext = opsional, input nya string contoh 'mp3', 'jpg' gak usah isi titik
         }
         * = musti pilih 1, mau pakek buffer atau stream
