    This handler is mainly to solve the problem of outputting a tremendous amount of logs to GUI applications in real-time.
 
    GUI applications use threading to display content while listening for user input (button click, key pressing, mouse scroll).

    processing to display a tremendous amount of logs to the GUI widget will lock a thread for quite a long time. 
    During this time, no user input will be handled and the app seems unresponsive.

    This significantly reduces the overhead on the widget side and makes the app responsive. 
    The solution is implemented in the new `StreamHandlerWithBuffer` which is inside `logger_tt.handlers`. 
    There are 2 steps to use this handler.

      For `buffer_line`, to avoid the last lines of log not printed out as the number of line is below threshold, 
      you should set `buffer_time` to a certain number too.
