Class describing a custom conversion curve between the command input,
usually the angular velocity, and the correspondent output thrust force.
Here the inverse of the conversion function can be computed so that the
command for the desired thrust force is retrieved.
The input vector corresponds to sampled values for the command input, and
the output vector corresponds to the sampled values for the correspondent
This information is usually available in the datasheet of the thruster's
