Create Directories Automatically in Notebooks

Running this line will result in No such file or directoryError in file(con, "w") : cannot open the connection

We can insert a create directory function above this line, e.g., dir.create(paste0(project_path))

Similarly, do the same before this line https://github.com/sailuh/kaiaulu/blob/ffd5f300e0c66c70ccc2beefcb7ab7da9ee9408c/vignettes/text_gof_showcase.Rmd#L140C19-L140C19

I think the bigger consideration here relates somewhat to #230, which is thinking through the folder organization more carefully for both rawdata and analysis in Kaiaulu, including reusing files across Notebooks, which your project is an example of.

The config and the project folder organization have evolved a bit since the config was last refactored (neither of these Notebooks even existed then). I will give it some thought. Feel free to add any other references where code breaks due to the absence of not making new folders.
