Ported StereoVOExample_large and Edits to StereoVOExample

[CodeXTL]

Ported the C++ StereoVOExample_large to a Python Notebook. The new notebook example is functionally the same as the C++ example with some additional explanation spread throughout.

Update(s):

• The main difference is that data files are downloaded from the GTSAM Github rather than creating another data folder just for the Python examples. This also makes the notebook easier to use in Colab.
• Also made some minor changes to StereoVOExample.ipynb

Check(s):

• Checked the results of the C++ example and the newly ported notebook example, and they match
• Running make check passes all tests.

Very cool, some comments, and some that we discussed in person

Still some things that we discussed that are not there (separate parsing from adding to FG), and plotting, but I'll assume you're still working on this. Just request a re-review via Github when this is ready.

@dellaert Everything should be ready now!

Update(s):

• Added cell tags so unnecessary cells (copy right, Colab env check) are not rendered by MyST.
• Shifted Google Colab button to be right under the main title
• StereoVOExample_large.ipynb specific changes:
  • Made large revision to StereoVOExample_large to have more comprehensive explanation
  • Separated code for parsing and adding to FG
  • Added plotting to visually analyze the end result using Plotly
• StereoVOExample.ipynb specific changes
  • Minor updates/polishes to explanation

Very cool! Please make sure both notebooks are restarted and you have "run all"? I can't merge until this is done, as there will be no outputs on website.

@dellaert I did a quick check and ran all again, and all cells that outputs something should now have an output. As a side note, I also checked the notebooks by viewing them on Github, and I noticed that the plotly figures didn't render; I'm pretty sure this is an issue with Github because the figures render correctly on my local deployment of the MyST site and I can see the pyplot data in the output when I view the notebook as a text file. So, everything should be all good!
