Feature Request -- Add a Convenient Way to Export the Mode Shapes

[jjonkman]

While ACDC provides a convenient way of automating the generation of Campbell diagrams and visualizing shapes using OpenFAST, it is not currently possible to export the mode shapes for visualization in, or comparison to the results from, other tools. It would be great to add a feature to export the magnitude and phase of the mode shape (deflection/rotation) at each structural analysis node (of BeamDyn, ElastoDyn, SubDyn) relative to the undeflected state.
