Live plotting of scan data happens in true real-time without lagging or blocking the interactive terminal. #408

Currently BlueAPISession uses WebSockets to listen for live data and these data events are received and processed on a background thread. However, Matplotlib strictly requires that all visual updates happen on the main thread. Trying to inject plotting inside feedback result in exception(I forgot to note down the error).

Goals

Acceptance criteria : What journeys should the user be able to complete to consider your feature done
Be as specific as you can, check them off once they work. Add more if you find more requirements during development. Issue should only be considered done after all of them are checked

• The interactive plot updates at a reasonable rate when new scan data arrives, rather after the at the end of scan.
• Plot updates are driven by incoming DataEvents, allowing us to remove the continuous background polling timer.
• The solution is thread-safe (no Matplotlib/GUI issues when scan are running).

Tasks
