sdlGameControllerGetButtonFromString function
Convert a string into an SDL_GameControllerButton enum.
This function is called internally to translate SDL_GameController mapping strings for the underlying joystick device into the consistent SDL_GameController mapping. You do not normally need to call this function unless you are parsing SDL_GameController mappings in your own code.
\param str string representing a SDL_GameController axis
\returns the SDL_GameControllerButton enum corresponding to the input
string, or SDL_CONTROLLER_AXIS_INVALID
if no match was found.
\since This function is available since SDL 2.0.0.
