[Fix] plot_indices

[Schiano-NOAA]

Make changes per issues #212 & #214

A new function gets created so that we can do the same plotting for other observed and predicted plot comparisons.

I also made an adjusted to process data so that the resulting df indexing variables are all character format.

@sbreitbart-NOAA for some reason, exporting the rda for plot_indices is not working now. Could you ID the issue and potentially fix it? It might be due to the facetting, but I'm not sure.

Here is an example:

plot_indices(example_data, make_rda = TRUE)
Error in if (file.exists(fs::path(dir, "captions_alt_text.csv"))) { : 
  argument is of length zero

The plot_indices.R file isn't up-to-date with that on the main branch, which contains the new key quantities extraction/insertion pipeline. Try a rebase?
