Remove flaps on main wing for fixedwing model when flying in mode 1.
The rationale is that flaps add a countertorque to what is actually desired.

Enabled full control over actuator surfaces for the fixedwing model under control mode -1.

In this mode, the setpoint for the fixedwing is a 6-long vector, with each element corresponding to control over:
1. Left Aileron [-1, 1]
2. Right Aileron [-1, 1]
3. Horizontal Tail [-1, 1]
4. Vertical Tail [-1, 1]
5. Main Wing [-1, 1]
6. Thrust [0, 1]

Fix package data again.

1. Fix for numpy check not executing properly.

Actually fix missing package data in the package.

The first release on GitHub!
