Add Strain Example from MHKiT-Python

[simmsa]

Use MATLAB's Markup syntax (similar to Markdown) to create a Livescript example
in .m format. This format allows version control diffability while maintaining
Livescript functionality when opened in MATLAB.

The Markup specification is documented here:
https://www.mathworks.com/help/matlab/matlab_prog/marking-up-matlab-comments-for-publishing.html.

This approach is forward-compatible with MATLAB R2024b's new plain text
format for Live Scripts:

To hedge against MATLAB removing support for Markup it is also
recommended to generate the .mlx and html files.

@MShabara and @akeeste this is ready for review. Right now this just mimics the functionality from the MHKiT-Python Strain Example: https://github.com/MHKiT-Software/MHKiT-Python/blob/main/examples/strain_measurement_example.ipynb

@simmsa a couple minor fixes:

• The images "resulting_loads_resized.png" and "global_cs_resized.png" have their names swapped. Once the names are switched, the images will match the filenames and they will be referenced correctly in the .mlx and .m files
• some subtitles from the python notebook are included in the mlx but don't format quite right
  • "90 degree rosettes"
  • "Alternate equations for 120 degree rosettes"
  • "Define equations for normal force, moment, and torsion"

Otherwise all the calculations and plots look good and match the python example.

On file formats--A diffable livescript would be great, but it seems like MATLAB is a few releases away before that's widely supported in the MATLAB GUI itself. Though publishing the .m file straight to html is easy and can give the same advantage. I don't ever use the publish functionality, but it was pretty easy to click through and get a nicely formatted HTML file. Could the publishable .m file replace the mlx files entirely? A user could quickly publish the .m file (or view the documentation) to see plots and comments in line, while also having the code readily accessible in a familiar format.
