BB transporter load_parameters_from_yaml fails #51

The tests of the load_parameters_from_yaml in the following file

https://github.com/SDU-Robotics/sdu_controllers/blob/main/tests/tests.cpp

does not consider that some of the joints can be fixed.
For the breeder blanket robot, the assertions are as follows:

const RobotParameters &p = *params_opt; REQUIRE(p.dof == 7u); REQUIRE(p.mass.size() == p.dof); // will fail REQUIRE(p.com.rows() == static_cast<int>(p.dof)); // will fail REQUIRE(p.com.cols() == 3); // joint_1 is prismatic REQUIRE(p.joint_types.size() == p.dof); REQUIRE(p.joint_types[0] == ForwardKinematics::PRISMATIC);

The marked lines will fail since we introduced an eigth joint that is fixed.
This means that p.dof is 7, while p.mass.size() and p.com.rows() are 8.
