Hey @pzierahn

Health has been updated to 4.0.0 and has support for adding workouts on Android and iOS using the writeWorkoutData instead and users should now use this function for workouts. However, due to the nature of the enums HealthDataType I will add an exception to the writeHealthData if uses try to add workouts using this function.
