Small GUI for File Management and Process Edit

[bradleeharr]

I created a small GUI using Tkinter that might help with running, file selection, and plotting.
The inputs go directly into the args for the main run script, similar to the original usage

The changes also add a small change to the process code

 print("Rising Edge idx: ", rising_edge_idx)
 print("Falling Edge idx: ", falling_edge_idx)

  if self.stateful_rising_edge == 0 and len(rising_edge_idx) > 0:
      # This is the first chunk with a detected beep, just set up the initial state
      self.stateful_rising_edge = rising_edge_idx[0]
      self.stateful_index += samples.size + 14
      return
