docs: Search bytes from big file faster with realtime result callback<br>
  <br>
  This callbacks the result in real time, but since the concurrency is
  inferior to #searchBigFile,so the execution speed is slower than
  #searchBigFile
  
  @param f
  targetFile
  @param searchBytes
  sequence of bytes you want to search
  @param listener
  callback for progress and realtime result
