Problem: Packed Loads Doesn't have a Reference Example in /docs/examples

[michael-okeefe]

Description

It would be good to have examples demonstrating how all of the major features work in the docs/examples directory. Although there is an example that is run via the regress.py test, it is a bit more complex as it transforms regular load files into packed load files. That is an excellent test of the functionality but it might be nice to have a much simpler test example at the top level as a reminder of how the file is set up (both the TOML and the packed loads csv).
