Mitiq GUI

[natestemen]

Some brainstorming from community call with @bdg221 @Aaron-Robertson:

Initial ideas:

• a way to interactively explore stacking QEM techniques (checkboxes for techniques)
• sliders to control noise levels for various noise profiles or import noise models from hardware
• resource estimator for how many circuits need to be run
• progress bar for larger simulations/runs

Implementation ideas:

• provide a jupyter notebook with interactive widgets
• some sort of "pop up" interactivity when calling mitiq.explore_techniques (say)
