Adding functionality without changing the MAVSDK library

[ygratz]

In order to use MAVSDK in an application, I need to follow version control requirements. To comply with this, I can take a given MAVSDK version with a given tag. The problem is, that sometimes I do need to make changes\adjustments in the given functionality. For example: the correction in the action.takeoff() to change mode to guided. Is there a correct way to add such functionality to my application, while not changing the given MAVSDK tagged library I'm using? As anyone encountered this before? If not, is it possible to add such a gateway to allow this?
