Improve "Code and sample data" section

1. It only lists .ipynb and \data files. Many chapters also rely on the \output files (created in Chapter 1), however, I assume that some reader will only try to run some chapters. Maybe we could make copies of some files from \output to \data? Or you have some better idea?
2. "landsat.tif" is not in the \data folder of the repo (maybe some others are also missing)
3. Do we even use some of the files listed (e.g., yorkshire.json)?
4. Can you explain me how the ipynb files are created? Maybe I could modify our GitHub action to make them automatically...

1. You're right, thanks! Now corrected in the text (https://github.com/geocompx/geocompy/commit/d0eb98107dde873b2b385132bbcbe8d67ca1d205)

2. landsat.tif was in .gitignore, I now removed the entry from there. I checked and no other files are missing

[michaeldorman]

3. Right, thanks! Now removed yorkshire.json, there are no other unnecessary files as far as I checked

4. The .ipynb files are created using:

   for i in *.qmd; do
   quarto convert $i
   done

   (https://github.com/geocompx/geocompy/blob/main/convert.sh) It's a good idea if this can be automatic, thanks

@michaeldorman -- see https://github.com/geocompx/geocompy/tree/geocompy.

I think I was able to create a GitHub action that creates ipynb files and move them (and data folder) to a new branch. See https://github.com/geocompx/geocompy/blob/main/.github/workflows/prep-book-package.yml.

This GitHub action only starts when your commit message contains "update book package"

[Nowosad]

The above approach allows us to create GitHub releases (from the geocompy branch): see https://github.com/geocompx/geocompy/releases/tag/0.2.

@michaeldorman would you be able to update the data/code instructions in the book?

[michaeldorman]

Hi @Nowosad ,looks great, thanks! Perhaps the release can also contain the output directory? (according to note (1) in the first comment in this thread)

[Nowosad]

See it now: https://github.com/geocompx/geocompy/tree/geocompy

Let me know if there is something still missing. If not -- feel free to create a new release.

As far as I can tell this is solved, so closing, thanks @Nowosad 🙏
