Incorrect input mapping can lead to Crazyflie unindendently taking off when connecting

[stefanthorstenson]

Due to incorrect input mapping, the throttle is sometimes at 70 %, even though the connected gamepad is untouched. In this case, if connecting to the crazyflie, the crazyflie takes off and there's no chance to save it from crashing.

Suggestion:
Throttle must touch zero before Crazyflie is allowed to take off. This would give the user time to understand that the input mapping is incorrect, as well as being a safe design. It could also be coupled with some message to the user.

Switching between mappings while connected can also trigger this.

A suggestion is to use an arming button.
