WISDEM - Better use of MPI in v3.18

WISDEM's use of MPI was a bit clunky and out of date. Meanwhile, OpenMDAO's integration with MPI has improved significantly over the past few years. This update leans more on OpenMDAO, making using WISDEM in parallel more robust and simpler for both developers and users.

WISDEM - Fix WISDEM-ORBIT interface

Thanks to user feedback, it was apparent that the WISDEM-ORBIT interface was outdated and giving incorrect Balance of Station costs. This release primarily intended to fix that error, but also brings along other improvements that were queued for the next release, including:

Drivetrain bedplate length for geared turbines was off by 0.5 * D_hub (#512 )
Easier ability to set mass constraints for the tower and monopile (previously had to use user-customizations)
Fix out-of-date issues on Docs and plotting script for Example 02 (#576 )
Easily get performance tables (rotor performance, blade geometry, blade layup, tower geometry)
Shift the peak thrust shaving coefficient from a modeling options file to ps_percent under the controls: heading (consistent with ROSCO). This enables using it as a design variable.
Enabling user-specified design variables and constraints to have index-specific bounds

WISDEM - User customizations and improved optimization results

Highlights of WISDEM 3.17 are:

Greater ability for the user to provide input values for components to override internal WISDEM calculations. A new case was added to the 11_user_custom example demonstrating this new ability. More work along these lines will be forthcoming.
Noticeable improvement in blade design optimization convergence and quality of solution
Upgrade to latest release of ORBIT
Improved robustness of writing outputs to file, and ability to read them back in as a "restart"
Support for Numpy 2.0
Improvements in floating platform optimization with WEIS
Add turbine and bos capex costs as optimization merit figures
Fix bug in the proper accounting for blade mass in the tower top forces.
Fix bug that ensures that commissioning and decommissioning costs are included in LandBOSSE figures.
MPI bug fixes for Windows

WISDEM - General updates in support of WEIS Phase 2

The PR brings in several changes:
Blade structure can be parametrized in the thickness of each layer, not only spar caps and reinforcements
There are new blade constraints to support inverse design studies (desired blade mass, desired natural frequencies)
New example and documentation to support inverse design
Update of installation steps (mamba)
Turbine gearbox can be desired with a desired torque density
User specified DVs, figure of merit, and constraints in support of WEIS Phase II
Strengthening of the sub-optimization to determine pitch angle across wind speeds in rotor_power.py
Cd0 no longer hard coded to 0
The list probably goes on

WISDEM - Support for new IEA Wind 22-MW turbine and other bug fixes

Highlights include:

Better ability to adjust thickness as a design variable
Changes to support the new IEA Wind 22-MW Reference Wind Turbine
Better handling of multiple airfoil polars in the yaml-input file
Remove duplicate code and capability between CCBlade and AirfoilPrep (AirfoilPrep has been fully removed)
Fix bug in blade cross-sectional area calculation. Instead of doing this in PreComp, it is now done as a layup summation.
Fix bug in sizing of main bearings for select drivetrain configurations

The next development tasks will involve more significant refactoring of the code to allow user-definitions of optimization problems and component mass / cost / stiffness values!

WISDEM - Improved FloatingSE optimization and bug fixes

This is a minor release that includes:

Careful and methodical improvements to the optimization approach, robustness, and results in FloatingSE. We still strongly recommend floating platform design with WEIS (in the frequency or time domain), but FloatingSE is improving as a starting point thanks to the work of @dzalkind
Bug fix so that the hub and nacelle center of gravity and moment of inertia calculation accounts for blade cone angle
Improved documentation and units consistency in the NREL Cost and Scaling Model
A handful of other bug fixes

WISDEM - v3.9: A bundle of bug fixes

This release has a bundle of bug fixes. Some of these have been long standing issues, others are new items that have arisen due to backward incompatible changes in upstream libraries. Improvements include:

Improvements in the robustness of the meson-based build system that appeared in the last release
Fixes for upstream library changes in pandas, openpyxl, openmdao, numpy, and others.
Fixes in precomp preprocessor of composite blades
Fixes for parallel performance
A more consistent approach to blade planform interpolation based on the pchip-algorithm
Many "backend" changes in configuration files, docs building, and more.

WISDEM - New GUI and build system

This release has three main elements:

A new GUI library, DearPyGUI, takes the place of pyside2. The functionality so far is exactly the same. The benefit of the new approach is that it will be easier to add capability, such as output variable explorer and graphs. The dependencies are also simplified.
A switch to the meson build system, as that seems to be the best approach following NumPy's disappointing deprecated of their distutils. Both pyoptsparse and scipy have also made this switch. Hopefully this is behind the curtain for most users, but there may be some fragility to overcome.
Fixes to accommodate many sudden incompatibilities with third-party libraries.
