Fix #149, crash when removing specific points

Right now, this does not work! For example the following test case fails:

def test_pose_remove_legs(mediapipe_poses_test_data: List[Pose]):
    points_that_should_be_hidden = ["KNEE", "HEEL", "FOOT", "TOE"]
    for pose in mediapipe_poses_test_data:
        # pose_hide_legs(pose)
        pose = pose_remove_legs(pose)

        for component in pose.header.components:
            point_names = [point.upper() for point in component.points]
            for point_name in point_names:
                for point_that_should_be_hidden in points_that_should_be_hidden:
                    assert point_that_should_be_hidden not in point_name

There is no such function pose_remove_legs in master / this branch

Right, it's in pose_evaluation

@AmitMY The fixed remove_components() and accompanying tests are now ready for review. Tested to ensure that it won't crash if you try to remove points from components that don't exist, or if you you remove both a component and a point IN that component, etc.
