Remove Frame argument in IodGooding constructor
For the three other IOD methods in Orekit (Gibbs, Lambert, and Laplace) the
Frame is defined in the
estimate() method signature. However, for Gooding method it is defined in the constructor.
For consistency between IOD methods, it could be interesting to move the
Frame definition from the constructor to the
estimate() method. Furthermore, it will allow having only one instance of IOD Gooding calculating orbits in different frames.
