Interactive mode

[Ben1152000]

There should be a way to use this tool interactively, enabling the user to explore a waveform without necessarily knowing what they want to see beforehand. I'd imagine this would be a mini-REPL, where the user could adjust the time window, visible wires, and any other parameters on-the-fly.

I have implemented the logic to adjust the time window by user, so moving forward please review my PR # 76 before I move forward on visible wires and other parameters

I have done with displaying visible wires, @Ben1152000 please tell me some other parameters to work on them and make Sootty more user interactive
