Missing import progressbar in async_down.py

[Imanflow]

If you try to run porder multiproc it fails with:

Traceback (most recent call last):
  File "/home/ec2-user/.local/bin/porder", line 11, in <module>
    sys.exit(main())
  File "/home/ec2-user/.local/lib/python3.7/site-packages/porder/porder.py", line 359, in main

    bar = progressbar.ProgressBar()
NameError: name 'progressbar' is not defined

Also, Pycharm marks sys in line 14 and time in line 68 as not imported.
