Extend trajectory with speed, velocity, acceleration

We propose to extend the trajectory definition with additional optional attributes like this:

struct trajectory:
    points: list of pose_3d = [defaulted]
    time_stamps: list of float = [defaulted]
    speeds_longitudinal: list of float = [defaulted]
    translational_accelerations_longitudinal: list of float = [defaulted]
    translational_accelerations: list of translational_acceleration_3d = [defaulted]
    translational_velocities: list of translational_velocity_3d = [defaulted]
    orientation_accelerations: list of orientation_acceleration_3d = [defaulted]
    orientation_rates: list of orientation_rate_3d = [defaulted]

A minimum subset for the next standard version would be

struct trajectory:
    points: list of pose_3d = [defaulted]
    time_stamps: list of float = [defaulted]
    speeds_longitudinal: list of float = [defaulted]

Use cases:

• More constraint trajectories to narrow down the solution space
• Parking trajectories with negative speeds
