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.

fix(ElemPerf): fix wrong writting of properties

See merge request rotare/rotare!5

fix: set true calculation of reynolds number

See merge request rotare/rotare!4

calculate reynolds number exact value in indvel.m
use its exact value when possible, if not use an approximation in ElemPerf.m

Add upstream velocities

See merge request rotare/rotare!3

fix(config): fix caradonna use of airfoil polars
