Add confirmation step to run.py

[ClayMav]

Description

When we get to competition, we will want to start the drone and wait for a signal to takeoff and run the flight code, so our start state will be a no action state, and upon user input, will trigger a move to the takeoff state.

Requirements

In run.py, utilize the threading library to:

• Add ability for user to submit user input to start the state machine by changing the state to takeoff
• Enable run.py to join flight and vision when state changes to final, stop, or error
