ENH: Create aerodynamic_surfaces parent class

[Gui-FernandesBR]

Is your feature request related to a problem? Please describe.

Create a new class to handle all the aerodynamic (drag and lift) operations on rocketpy, saving some codeline of rocket class and starting

Describe the solution you'd like

• Create the aerodynamic_surface abstract class
• Use setters and getters to allow changes to aerodynamic surface definition parameters (for optimization and control)
• Move the Prandtl–Glauert transformation (beta) to the aerodynamic_surface abstract class
• Create unit tests
• Move Drag Coefficients definition from the rocket class to the new aerodynamic_surfaces class
• Fix legend on plots created by draw() methods
• Plot airfoil information when it's available (Airfoil Rocket.allInfo() method #144 )
• Remove the addTail, addNose, addFins and similar methods from the rocket class
