Edits to `pyproject.toml` for conda build compatibility

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.

This release has three main elements:

- A new GUI library, [DearPyGUI](https://dearpygui.readthedocs.io/en/latest/), 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.

This release is a collection of minor bug fixes and incremental feature improvement. This includes:

- Multiple bug fixes around jacket design and cost estimation
- Installation robustness with `setuptools` and simpler instructions for new users. There is still future work here to move away from Numpy `distutils`
- Consistent gust velocity definition across modules
- Propagation of fiber orientation angle though blade data structure
- Generator design workflow improvements
- Drivetrain design workflow improvements
- Blade cost model improvements and bug fixes
- Full rotor-tower-monopile design example

A follow-on bug fix on top of the changes in v3.6 relating to hydrostatic load calculations and the variable namespace in postprocessing scripts.

New capability around segmented blades and jacket design for fixed-bottom offshore structures has been added. A number of bug fixes, especially in the substructure and tower design, have been fixed.
