Velocity not limited for the diff drive controller

[IDavGal]

Description

The andino_controllers.yaml configuration file specify no limits in the linear/angular velocity. According the motor's description its max velocity is 90 RPM, given the wheel radius this would translate to roughly 0.33 m/s linear vel.
The diff_drive_controller handles both velocities limits separately, so the border case in which linear_vel + angular_vel translates to a higher motor velocity than 90 RPM is not considered by this calculation.

There is an open PR in ros2_controllers addressing this issue, although is currently pause.
I'll try to either bump it up or address the issues myself.

I should run a local test in the real robot and provide a real-based approximation, wdyt?
My estimation is that we are going to be below 0.5 m/s without effort.
