Complete refactoring of the updateupstreamvel function in order to
facilitate inclusion of new models.

Added Single StreamTube model and a more exact calculation of the
streamtube constraction using the MST model.

The contraction should be calculated based on the **last element**
position and not the actual rotor radius.

In some edge cases, an element of the aft rotor can fall in between the
contraction calculated from the previous rotor's last element and the one
calculated from its tip radius. When this happens, the velocity is
poorly interpolated and brought to 0 for this element on the aft rotor.
This not only skews the results, but also lead to issues with the
current implementation of the indfact solver, which only looks into
Op.speed~=0 and into the airspeed for each individual elements.

- Adapt upstream velocity definition
- Proper calculation of inflow velocity for second rotor
- Modify Results class to store multiple rotors
- Adapt BEMT indvel

This completes the work started in !4 by implementing the true
Reynolds recalculation for the other three solvers.

Note that special care had to be implemented in Stahlhut solver in order
to ensure proper numerical resolution of the solution.
