feature: plot timestamps from outfiles

[roycewilliams]

Hashcat supports the following --outfile-format format elements:

  # | Format
 ===+========
  1 | hash[:salt]
  2 | plain
  3 | hex_plain
  4 | crack_pos
  5 | timestamp absolute
  6 | timestamp relative

Note especially the timestamp data. For both pentesting and general/academic research, it would be very useful to be able to graph cracking progress along a time axis.

There is some complexity around the configurable nature of the outfile fields format, so there would need to be a way to tell graphcat how to interpret the outfile.

Agreed. Will work on it
