No OpenMDAO and support newer python versions

[gbarter]

• Adds Python 3.12, 3.13.
• Removes WISDEM api file and openmdao dependency
• Move matplotlib to optional [plot] depedency since it is only used in the code in the plot_array function.

Thanks for making these updates to accommodate changes in WISDEM, @gbarter! I left a few really minor comments. Would you be able to also add a note to the changelog? It also seems like this is a good candidate for a patch release to ensure a smooth transition for the updates in WISDEM, or is the WISDEM release with the ORBIT changes coming at a later point in time?

Yes, an incremental patch release is what I had in mind too!

This looks good to me, thanks for updating the WISDEM-ORBIT interfacing, @gbarter!

Thanks @gbarter for suggesting this changes and thanks @RHammond2 for chiming in. I'm ok with merging this into dev and then I'll do another incremental release into main by the end of this week.
